INTRODUCTION
Thank you very much for purchasing iCLOCK or iCLOCK dp, Redundant
Multiple Clock Synthesizer & Video Reference Generator, from MUTEC!
About this Manual
The whole manual is related to both versions in general, iCLOCK and
iCLOCK dp. The individual differences are mentioned in the according
sections and chapters.
The structure of this manual refers to the normal process of installing
iCLOCK in a standard audio/video studio environment. Thus the chapters
are ergonomically sorted to provide a fast set-up. Before first power-on we
recommend to read the chapters INTRODUCTION and BRIEF INSTRUCTIONS
to get to know the general functionality of iCLOCK and to reach a fast
system integration.
The following chapters OPERATION and iCLOCK TechnologY describe
individual functions which enable the adaption of iCLOCK to every studio
environment. The chapters APPLICATION EXAMPLE and APPENDIX include
descriptions of favorable studio set-ups as well as all technical information.
The grey boxes contain supplementary
information for the corresponding sections
in the text columns. The content of the
individual box refers to the description in
the text column beside the box.
Boxes which contain a triangle
with an exclamation mark should
be read carefully! These include
additional information which are of major
importance for the functional descriptions in
the text column.
!
If there are any uncertainties when operating the units which can not be
cleared up by the content of this manual, please feel free to contact your
local dealer or MUTEC directly. All contact details are included in chapter
WARRANTY REGULATIONS located at the beginning of the manual.
General Function Description
iCLOCK is a synchronizable, high-precision clock generator which is
designed to be the reference in digital audio and video studios as well
as broadcast and television stations. Based on a totally new concept
of frequency generation, developed by MUTEC, the unit offers an
unchallanged flexibility for synchronization of different devices to one
house clock. On this occasion iCLOCK breaks traditional, unflexible forms
of chaining input and output signals and allows for the first time their
completely free combination and scaleability.
iCLOCK‘s philosophy is addressed to provide the highest possible failure
safety for all outgoing clock signals which is needed especially for
broadcast stations or centralized clock distribution systems. With regards
to this functionality up to 3 independent external references can be autodetected and locked in a user-defined sequence without any phase-jumps
or interruptions in the outgoing signals. This applies also to external
clock frequency changes, e.g. from 44.1kHz to 48.0kHz or reference clock
changes, e.g. from video to GPS or AES11. Even if all external references
are lost, iCLOCK synthesizes the outgoing clock signals based on the
last incoming frequency constantly. If the absent reference clock returns
the synthesizer will lock gradually again based on iCLOCK’s SoftReLock
functionality which ensures interruption-free adjustments of all outgoing
clock signals. In this case a continous clock supply for all connected devices
is guaranteed during any operation mode.
For todays audio/video productions a precision synchronisation of the used
audio and video equipment is imperative. To reach the highest value of
accuracy the involved clock signals need to be synchronized and converted
without any phase drift. Therefore iCLOCK offers a unique, automatically
working signal management which observes the phase relationships of all
input and output signals and takes care of adjustments aligned to
AES11-1997/2003 and EBU R83-1996.
Using DDS-coupled frequency generation and latest DSP-based filtering
technologies in combination with an extremely low-jitter clock basis of
< 10ps (RMS), iCLOCK eliminates the jitter of incoming reference signals
completely. This ensures highest possible jitter attenuation for all outgoing
clock signals. As a result the synchronization of connected devices is much
more reliable and the sound quality of every AD/DA converter will be
increased significantly.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Differences between Software V2.10 and V2.11
Both versions include the preset management as new functionality, which
was inquired by several professonal MUTEC customers (see page 28).
Using software V2.10 or V2.11 depends on the alarm interface you have
already installed or you plan to install. Software V2.10 supports only the
older interface iC-ALARM (ordering no. 8005-056), whereas software
V2.11 supports only the new iC-ALARM/GPI (ordering no. 8005-066).
The iC-ALARM/GPI interface offers same basis functionality like the iCALARM, but the new iC-ALARM/GPI interface allows for switching over the
different presets via its GPIO function (see page 31, 32).

These universal input terminals allow for applying various external clock
signals for synchronizing the internal clock synthesizer. All clock formats
supported by the system can be received at any of these inputs. These two
inputs and INPUT 3 can be synchronized by the synthesizer in a freely configurable sequence. The impedance of each input is 75 Ω and can be switched
off internally for chaining devices, see the »Switching-off the Termination
of the universal Clock Inputs« section in the appendix.
3 ALARM OUT
The iC-ALARM output is optionally available (item no. 8005-065). Refer to
the EXTENSIONS chapter for a short overview.
4 INPUT3 (AES/EBU)
A balanced digital AES/EBU signal can be applied to this input for synchronizing the internal clock synthesizer. The signal must comply with
AES3 – 1992 (R1997) or AES11 – 1997.
Both input terminals are isolated from
ground to avoid interference from the
connected clock line. This applies to all clock
references except video! Is a video signal
selected as reference the corresponding
input will be connected to ground automatically.
If this does not comply with the electrical
studio purposes, the ground connections of
both inputs could be linked permanently by
setting jumpers on the mainboard. Refer to
the »Connecting the universal Clock Inputs
to Ground« section in the appendix for a
short instruction.

5 PAL/NTSC VIDEO OUT
SD bi-level PAL and NTSC composite video sync signals are sent from these
outputs. After installing the optional P/NVSG-02 video sync generator (item
no. 8010-010), a separate video format can be assigned to each output pair.
Associated output pairs are arranged on top of each other.
If a HD tri-level sync signal is applied to a reference input, the incoming
reference can be distributed through the PAL/NTSC video outputs.
The individual BNC terminals of an output pair are marked as A and B; this
allows, for example, for a simple documentation of the connected devices.
Refer to the »Synchronizable and generatable Clock Rates« section in the appendix
for a full list of all Word Clock, AES/EBU and
S/P-DIF clock rates that can be generated.
6 WORD CLOCK OUT
These outputs send Word Clock, Word Clock x 256 signals and film / video
frame / field clock rates. Each of the output pairs can be assigned with a separate clock rate. Associated output pairs are arranged on top of each other.
The individual BNC terminals of an output pair are marked as A and B; this
allows, for example, for a simple documentation of the connected devices.
7 + 8 AES/EBU OUT1, AES/EBU OUT2
These outputs send a balanced digital AES/EBU audio or blank frame signal
compliant with AES3 – 1992 (R1997) and AES11 – 1997. Each of the output
pairs can be assigned with a separate clock rate, and the channel status bits
can be edited individually. The rear-panel outputs are marked as AES OUT 1
and AES OUT 2, the individual output terminals as »A« and »B«; this allows,
for example, for a simple documentation of the connected devices.
9 S/P-DIF OUT
These outputs send an unbalanced digital S/P-DIF audio or blank frame
signal compliant with IEC 60958. The channel status bits can be edited. The
individual output terminals are marked as A and B; this allows, for example,
for a simple documentation of the connected devices.

INSTALLATION
Content of the Box
The unit was packed carefully. Nevertheless we recommend to check the
content directly after opening the package:
!
Before Powering Up
1 x iCLOCK / iCLOCK dp
1 x Power cable, 2 x power cables for iCLOCK dp
4 x Rubber feet
1 x Manual
1 x Registration card
The condition of the packaging
material and the device should
be checked carefully additionally. If there
are any damages please refer to SAFETY
INSTRUCTIONS, Initial Operation, and
WARRANTY REGULATIONS.
Placing the Device
Before installing the unit the section SAFETY
INSTRUCTIONS located at the beginning of
this manual should be read carefully.
The unit should be set up as closely as possible to the devices to which it
will be connected, so as to avoid excessive cable lengths. Use the 4 rubber
feets enclosed with the appliance and stick them symmetrically on the
bottom side of the unit to protect the enclosure and supporting surface
from being damaged.
The device can be mounted into a standard 19“ rack and will require 1
unit. In this case, the rubber feet cannot be attached. Install the device so
that one unit of rack space is left free both above and below the device to
allow for sufficient ventilation! The mounting depth including the terminals is 240 mm/9.45“ for iCLOCK and 280mm/11.02 for iCLOCK dp. Another
60 mm/2.4“ should be added for the required cables.
Never expose the device and accessories to
rain, moisture, direct sunlight, or excessive
heat produced by radiators, heaters, or
spot lights! Sufficient air circulation in the
environment of the device must be ensured!
Additional slide-in rails on the rack inside are recommended for safe installation. This will also avoid long-term mechanical deformation of the housing.
Wiring the Word Clock and Video Interfaces
To allow for synchronization of signals, the interfaces of all devices involved
must be properly connected to each other, so as to ensure a logical signal
flow. Always be sure to connect the Word Clock outputs of iCLOCK to the
according inputs of the devices you wish to synchronize! Cable lengths should
be kept as short as possible to minimize signal losses and/or interference!
For the transmission of Word Clock or video signals electrical, asymmetrical
cables with a resistance of 75Ω and BNC connectors on both ends are used.
Typically, such cables are marked »RG-59U, RG59B/U«.
Additionally, you should make sure that the Word Clock or video inputs to
be connected to iCLOCK’s outputs have a 75 Ω terminating resistor! Most
Word Clock or video inputs allow for enabling/disabling the termination
with a so-called »termination-switch«, which may be located on the outside
or inside of the device.
For devices which have no termination of the Word Clock input, e.g. RME
Hammerfall with Word Clock i/o or Alesis BRC, you can use an additional
BNC-T piece to terminate the input. Plug the T piece with its center connector into the input of the receiving device. Then, connect the cable coming
from iCLOCK to one of the lateral connectors, and the other connector of
the BNC-T piece to a 75Ω resistor forming the BNC termination.
Basically, you should avoid »looping through« Word Clock leads by means
of passive BNC-T pieces to preserve the signal quality, as level drops will be
the result. If there is no other way to wire your set-up, please make sure
that all Word Clock inputs (except for the last device in the chain) have
their terminations disabled! In a serial Word Clock chain only the last clock
input should have a termination! Never connect more than three devices in
series to one output!
!
Clock Cable Lengths
It is imperative that the lengths of
all cables connected are largely the
same, as this is the only way to ensure that
all devices will be synchronized in phase
(exception: cable tolerances).
Please make sure that the cable used has a
resistance of 75 Ω, in compliance with the
specifications! If a cable with a different
resistance is used, a dramatic deterioration
of the signal quality can be the result! In
this case, the perfect synchronization of all
devices involved could be impaired.
We recommend using high-grade cables
with a good shielding for your clock signal
leads, in particular, if you need to transmit
Word Clock x 256 (so-called Super Clock)
signals over greater distances. In any case, a
length of max. 10 meters (approx. 30 feet)
should never be exceeded!

Wiring the AES/EBU and S/P-DIF interfaces
!
Cables for High Clock Rates
Especially when working with high
AES3/-11 clock rates well shielded
clock lines are imperative to avoid increased
radiation! Standard cables are nor-mally
useable for clock rates up to 50.0kHz. Special
shielded cable material should be used for
transfer of higher clock rates.
Connect the AES/EBU interfaces with the help of balanced electrical
cables equipped with XLR connectors on both ends. The specifications
stipulate a specific cable resistance of 110Ω (ask your retailer for a confirmation of this value when purchasing the cables).
Connect the coaxial S/P-DIF interface with the help of unbalanced electrical cables equipped with cinch connectors on both ends. The specifications
stipulate a specific cable resistance of 75Ω (ask your retailer for a confirmation of this value when purchasing the cables).
Since some manufacturers offer optimized
cables for the transmission of digital S/P-DIF
and AES3/-11 signals, it will be a good idea
to ask your retailer for specific cables.

GENERAL OPERATION
Menu Structure
The entire menu structure is based on the logical flow of events when deploying the iCLOCK in a standard audio/video-studio
environment. Therefore, starting with the menu main page, the menu pages have an ergonomically structured sequence and can
thus be called successively by repeatedly pressing the up button.

4 When the horizontal arrow has been positioned in front of the parameter to be changed, pressing the up/down buttons will first change to the setting mode (the arrow will change its shape). Subsequent pressing the ENTER button will confirm the changes, the arrow will return to its original shape. Pressing the ENTER key again will then move the arrow to the next parameter.
If no buttons are operated for approx.
30 seconds, the display will automatically

Menu main page
INPUT REF1, -2, -3
INPUT REFERENCE, shows an abbreviation of the clock source currently selected incl. its reference slot and its actual rate as a realtime measurement.
As display space is limited, the displayed value is automatically adapted
with regard to the decimal places and the frequency unit as follows:
Hz = hertz
k = kilohertz
M = megahertz
Refer to the »Selecting Clock Sources« section in this chapter for
information on individual sources.
STATUS (function)
Shows the current system status. STATUS provides information on the device
synchronization and possible system errors. Major functionalities are indicated through eight LEDs on the right hand side of the display additionally.
LOCKED
(status message)
LOCKED indicates that the system has synchronized to the internal video
reference generator or an externally applied clock signal. At the same time,
the blue LOCK indicator associated with the active clock input (INPUT 1 - 3)
will light.
FQ CHANGE
(status message)
FREQUENCY CHANGE indicates that a sync source change is occurring. This
can be a change between two externally applied clock signals or an automatically or manually performed change from an external to an internal
clock source (or vice versa). When the change occurs, the LOCK indicator
of the last clock source used will go dark, and the red HOLD indicator will
light. When the system has locked to the new source, the HOLD indicator
will go dark, and the associated LOCK indicator will light.
HOLD (status message)
HOLD indicates that an externally applied clock signal has either drifted
outside its permitted lock range (see the PULL RANGE parameter on the
GLOBAL 1/4 page) or is completely lost. In this case, the system waits for a
certain period for the signal to return before automatically changing to the
next clock source. This waiting period specified by the LONEREF parameter
on the GLOBAL 2/4 page.
!
Status Displays
When iCLOCK is running in INTERN
mode the first blue LED, LOCK REF 1,
will light and confirm the synchronization
of the synthesizer to the internal video
reference generator.
After first switching on, the synthesizer
needs approx. 30 seconds to achieve stable
synchronization. This depends on the time the
video reference generator needs for attuning
all components of its video output signal.
During this process the system re-locks
temporarily (the HOLD LED and the blue
LOCKED REF 1 LED are lightening alternately).
This has no relevance for system security.
The output clocks are constantly available.
CYCLESYNC
(status message)
CYCLE SYNCHRONIZATION indicates that the system is currently performing an automatic resynchronization. This function can be disabled on the
REF1–3 page or be enabled manually for individual clock source inputs.

OSCI FAIL (status message)
OSCILLATOR FAILED, indicates that the internal reference clock oscillator has
failed.

Error Messages
If one of the messages OSCI FAIL,
MAIN1LOST or MAIN2LOST is
displayed, safe operation is not guaranteed!
Contact the technician in charge
immediately!
MAIN1LOST (status message)
MAIN 1 LOST indicates that the primary supply voltage or the primary internal power supply have failed. If this status message is indicated, contact
the technician in charge immediately! The message is displayed only if the
iCLOCK is equipped with a redundant power supply (iCLOCK dp version,
item no. 8015-046).
MAIN2LOST (status message)
MAIN 2 LOST indicates that the secondary supply voltage or the secondary
internal power supply have failed. If this status message is indicated, contact the technician in charge immediately! The message is displayed only if
the iCLOCK is equipped with a redundant power supply (iCLOCK dp version,
item no. 8015-046).
OUTPUTs (function)
Here, the set clock rates of all outputs are displayed alternately as a
»ticker«. This allows for checking the settings directly with no need for
changing to the relevant menu pages.
The following clock signals or rates are factory defaults:

Selecting and activating Clock Sources
The REF1-3 page allows for selecting the clock source of the internal synthesizer. The clock formats supported by iCLOCK are listed in the adjacent table.
The factory defaults are REF1 = INTERN, REF2 = NO REF, REF3 = NO REF.
If one of the synchronizable clock sources is selected, the respective signal
format is marked with an index (1 + 2) referring to the two universal clocksource inputs INPUT 1 and INPUT 2. Thus, the input clock signals can be
routed freely to these two system inputs. The AES format, however, is an
exception as balanced AES/EBU signals can be received by INPUT 3 only.
!
Activating Clock Sources
After selecting a new clock source
under REF1 – 3, it is imperative to
move the cursor to the SYNC function and
to press ENTER for activating the selected
reference for synchronisation!
When selecting clock sources, the system proceeds logically. For example,
if the PAL1 source (PAL video on INPUT 1) has been selected under REF1,
it will not be available anymore for REF2 and REF3. This means that only
sources with an index of »2«, »AES«, »INTERN«, and »NO REF« can be
configured. Likewise, a clock source programmed for REF2 will not be
available for REF3 anymore.
If a clock source is routed to one of the REF slots it has to be activated
for synthesizer synchronization. Therefore the last modified REF slot
is displayed in the SYNC function menu automatically. Moving the
cursor to this position and pressing the ENTER button will activate the
synchronization process to the new clock source immediately.

Setting REF1 – 3
The most important clock source
in your studio environment should
always be assigned to REF1! This is critical
for proper completion of the CYCLE-SYNC
setting. Afterwards, the other REF slots
should be assigned with sources in a
hierarchical order.
REF 1, REF2, REF3 (function)
This function allows for selecting three clock sources supported by the system and for assigning them to a clock source slot. The sources will synchronize the system in their numeric sequence (REF1 → REF2 → REF3).
INTERN
(setting)
INTERNAL Selecting the INTERN setting synchronizes the synthesizer to the
internal video reference generator that supplies all audio clock signals in
compliance with AES11 and EBU R83. As internal synchronization is the ultimately selected source, no other sources will be left afterwards. Therefore,
when selecting INTERN for REF1, the REF2 and REF3 functions will automatically be assigned with the »NO REF« setting.

AES3/-11 rates in a range of 32…192kHz. The applied clock rate is recognized automatically. Both AES 3id or AES 11id compliant signals can be
applied. In addition, S/PDIF signals can be applied to this input and be used
for synchronization. Refer to the »Synchronizable and Generatable Clock
Rates« section in the appendix for a full list of all clock rates.
S/P-DIF1, -2 (setting)
S/P-DIF1, -2 allows for synchronizing the synthesizer to all audio-related
S/P-DIF rates in a range of 32…192kHz. The applied clock rate is recognized automatically. Both S/P-DIF audio or S/P-DIF blank frame signals can be
applied. Refer to the »Synchronizable and Generatable Clock Rates« section
in the appendix for a full list of all clock rates.
New References
For special-purpose applications, the range
or number of the sync-clock references can
be extended by means of a software update.
Practically any frequency or frequency
range between 1.0 kHz and 30.0 MHz can be

When applying Word Clock, GPS, Telecom,
DCF77 or MFS60 sources, both pulse and sine
signals will be accepted which allows for
processing even heavily slurred signals.
If an option supporting new input clock
formats is installed, these will automatically
be implemented by the system and will be

GPS 1, -2
(setting)
GPS1, -2 allows for synchronizing the synthesizer to all sources with
standard GPS rates (1.0MHz, 2.5MHz, 5.0MHz, and 10.0MHz). The actual
clock rate will be recognized automatically.
TELEC 1, -2 (setting)
TELECOM1, -2 allows for synchronizing the synthesizer to sources providing
the standard Telecom clock rates of 1.024MHz or 2.048MHz. The actual
clock rate will be recognized automatically.
DCF 77 1, -2

MSF601, -2 allows for synchronizing the synthesizer to sources providing a
MSF60 clock rate (60.0kHz). This reference is transmitted from Rugby / UK
with a range of approx. 1500kms. From April 1st, 2007, it will be transmitted from Anthorn.
HD-P- 1, -2
(setting)
HD-P-1, -2 allows for synchronizing the synthesizer to HD tri-level sync
sources with frame rates of 24Hz, 25Hz, 30Hz, 50Hz, 60Hz.
HD-N- 1, -2
(setting)
HD-N-1, -2 allows for synchronizing the synthesizer to HD tri-level sync
sources with frame rates of 23.98Hz, 29.97Hz, 59.94Hz.
NO REF
(setting)
Selecting the NO REF setting disables the respective clock-source slot. If, for
example, only two clock sources are connected to the device and REF1 and
REF2 are configured accordingly, assign the NO REF setting to the REF3 slot
in order to disable this slot for the automatic resynchronization function
(see also CYCLESYNC).
!
Displaying HD tri-level
References
When locking your iCLOCK or
iCLOCKdp to HD tri-level references, their
individual frame rates can not be displayed
correctly under »STATUS«, as it is the case
when locking SD bi-level references. This is
due to system reasons. But your iCLOCK will
be locked as it should be.
Refer to the »Synchronizable HD tri-level
Standards and Frame Rates« section in the
appendix for a full list of all synchronizable
and convertable HD tri-level standards and
frame rates.

As the synthesizer is capable of continuously
supplying the adjusted iCLOCK output
signals, even a manual clock source change
on an input (by replugging the clock lines) is
supported during operation!
It is not important whether the change occurs,
for example, from a PAL SD video signal to a
Word Clock or GPS signal. The set output clock
rates will not be altered; only the base rate
will gradually be updated to match the new
source using iCLOCK‘s SoftReLock functionality
(see chapter iCLOCK TECHNOLOGY).
SYNC (function)
Synchronization This function allows for manual or automatic synchronization of the synthesizer to selected clock sources assigned to the REF1–3
slots.
SEQSYNC
(setting)
SEQUENCE SYNCHRONIZATION This is the default setting when activating
the REF1–3 menu page. It indicates the standard reference synchronization
mode of iCLOCK.
REF 1, REF2, REF3
(setting)
If one of the REF1, REF2, or REF3 parameters is selected and confirmed by
pressing the ENTER button, the synthesizer will immediately synchronize
the clock source assigned to the corresponding REF slot. The output signals
are set or adapted to the new source within the period specified by the
LOCKTIME parameter (see GLOBAL 2/4 page).
CYCLESYNC
!
CYCLESYNC is not available when
the LONEREF function is set to HOLD
(see GLOBAL 2/4 menu page).
(setting)
CYCLE SYNCHRONIZATION With this setting, the input circuit querys the three
inputs for clock source reestablishment by cycling from REF1 to REF2 to REF3
and to the internal video reference generator automatically until a source is
available. The system‘s priority is programmed to the first reference slot (REF1).
Refer to »Sequence Synchronization and Cycle Synchronization« section in the
iCLOCK TECHNOLOGY chapter for details about SEQSYNC and CYCLESYNC.
Configuring the internal Video Reference Generator
The settings of the internal video reference generator and the four video
outputs available with iCLOCK standard version are configured on this
page. Two output pairs comprising one top-row and one bottom-row BNC
output each are available on the rear panel. These are numbered as PAL/
NTSC VIDEO OUT 1 and 2.

If the optional second video generator is
installed, it is necessary to split up the video
output pairs between the two generators.
Therefore, two jumpers have to be removed
from their socktes on the mainboard, see the
»Splitting-up the Video Ouputs for dual
Video Generator Operation« section in the
appendix.
!
Locking the internal Video
Reference Generator – 1
If PAL or NTSC SD video is selected
as external reference, the internal video
reference generator will be automa-tically
gen-locked by the reference source and
switches to the same video format! This guaranties correct phase relationships between
the video source and iCLOCK‘s generated sync
signals. A video format conversion is only
possible using the optional video generator
P/NVSG-02 (Order no. 8010-010) additionally.
With synchronization to PAL or NTSC SD bilevel video it is not possible to change the
clock reference (REF) of the internal video
reference generator!
(page name)
VIDEO OUT 1 + 2 indicates that the internal video reference generator sends
its signals to both PAL/NTSC VIDEO OUT 1 and 2. This means also that only
one video reference generator is installed.
If the optional second generator is installed, another menu page will automatically be added for it. The page names will change accordingly:
VIDEO OUT 1
VIDEO OUT 2
= internal video reference generator = optional video generator REF (function)
REFERENCE This function allows for setting the clock source of the respective video generator and can also enable video signal routing. The factory
default is INTERN.
INTERN (setting)
INTERNAL links the video generator to the internal reference clock oscillator. An extraordinary feature of iCLOCK is that the synthesizer can be synchronized to an external clock source independently of the simultaneously
enabled video generator. Therefore, only the audio-related clock signals
might be subject to any present clock source deviation while the video signals are output with the accuracy of the internal clock: In a way, the video
generator acts as »independent autonomous generator« within iCLOCK.
EXTERN
(setting)
EXTERNAL This setting synchronizes the video reference generator to the currently selected external clock source. Any signal or phase relations between
the input clock signals and the selected video format will be recognized automatically and be routed internally in compliance with AES11 and EBU R83.
18 > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > 88
ANHANG
\\\\\\\\\\\\\\\\\\
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
This function also ensures a redundant (failsafe) availability of the video
output signals. If the external source fails temporarily or permanently, the
video generator will continue generating its output signals based on the
last recognized clock rate. If the external source returns to operation, any
differences to the previous rate will gradually be corrected to maintain
flawless on-air operation in e.g. broadcasting environments.
DIST (setting)
DISTRIBUTION This setting allows for forwarding the input video signal
to the video outputs using a hardware bypass. The signal is refreshed by
the video generator output amplifier to ensure a suitable output level; no
other modifications are made to the signal. If the DIST setting has been
selected for REF, the FORMAT and VIDEO TYPE functions cannot be selected
anymore. This is because the video output format is determined by the
input video reference signal.
In this mode, the synthesizer synchronizes to the input video signal to provide the output of phase locked audio clock signals.
FORMAT (function)
FORMAT This function allows for selecting the video format generated and
output by the video generator. The factory default is PAL.
PAL
(setting)
PAL With this setting, the video generator produces a PAL-B/G standard definition (SD) video signal compliant with the PAL/CCIR video standard (25 fps,
625 lines, 15,625.0 Hz line frequency). Depending on the REF and VIDEO
TYPE settings, this signal can be output as Black + Burst or composite video
sync. Even when a HD tri-level source is choosed as reference (HD-P-1 / 2), the
PAL setting is possible. Thus the internal video reference generator directly
converts incoming HD references with frame rates of 24Hz, 25Hz, 30Hz, 50Hz
or 60Hz into PAL SD video using its unique cross-locking functionality.
NTSC
(setting)
NTSC With this setting, the video generator produces an NTSC standard
definition (SD) video signal (29.97 fps, 525 lines, 15,734.25 Hz line frequency).
Depending on the REF and VIDEO TYPE setting, this signal can be output as
Black + Burst or composite video sync.
Even when a HD tri-level source is choosed as reference (HD-N-1 / 2), the
NTSC setting is possible. Thus the internal video reference generator directly
converts incoming HD references with frame rates of 23.98Hz, 29.97Hz or
59.94Hz into NTSC SD video using its unique cross-locking functionality.
Refer to the »Synchronizable HD tri-level Standards and Frame Rates« section
in the appendix for a list of all convertable HD standards and frame rates.

Locking the internal Video
Reference Generator – 2
When running the internal video
reference generator in EXTERNAL mode, the
external reference signal may not deviate
more than ±30 ppm from its nominal clock
frequency! Do not try to lock the video
generator to pull up/down clock rates - its
video signal would be destroyed!
DIST does not provide redundancy for the
video outputs. If the external video reference
source fails, the video outputs will fail, too!
!
Locking the internal Video
Reference Generator – 3
When externally synchronizing the
video reference generator, the lock
and varispeed ranges of the synthesizer will be reduced to ± 30 ppm! Thus,
enabling the pull-up/down and varispeed
factors is not provided in this mode. If,
however, these settings are made, the video
generator will automatically enable internal
synchronization.
When locking the synthesizer to the
internal video reference generator or when
locking the video reference generator to
an external applied reference source, a
synchronization time of approx. 30 seconds
for attuning all components of the video
output signal is required.
During this process the system re-locks
temporarily (the HOLD LED and the blue
LOCKED REF 1 LED are lightening alternately).
This has no relevance for system security.
The output clocks are constantly available.
VIDEO TYPE (function)
VIDEO TYPE This function allows for outputting the previously selected
video format as Black + Burst or composite video sync signal. In addition,
when selecting composite video sync, one of two different output levels
can be set (see below). The factory default is BLACK + BURST.
BLACK + BURST
(setting)
BLACK + BURST With this setting, the signal of the previously selected
format will be output as Black + Burst signal. Refer to the »Technical Data«
section in the appendix.
COMPOSITE SYNC 0.3V
(setting)
COMPOSITE 0.3V With this setting, the previously selected video format is
output as composite video sync signal with a negative sync signal level of
300 mV (0.3 V).

Configuring the Word Clock Outputs
Due to the internal signal phase corrections
the synthesizer can re-lock temporarily when
switching Word Clock clock frequencies.
This does not affect the output signals or
functionality of iCLOCK.
The WCLK OUT 1–4 display pages allow for configuring the eight wordclock
outputs provided by the iCLOCK standard version . Four output pairs
comprising one top-row and one bottom-row output each are available on
the rear panel. These are numbered as WORD CLOCK OUT 1–4. The BNC
terminals making up a pair are marked as »A« and »B«, thus allowing for a
simple documentation of the connected devices.

GPS / Atomic Clock + Audio Player
References
As so-called GPS or atomic clock references,
the iCLOCK and iCLOCKdp are able to lock
and generate the following frequencies:
1.0Mhz, 2.5MHz, 5.0MHz, 10.0MHz
Furthermore, the iCLOCK and iCLOCKdp are
able to generate the following basic clock
rate used in e.g. CD players:
16.9344MHz
This clock signal can be used to replace a
CD player‘s internal system clock with the
16.9344MHz clock signal generated by the
iCLOCK or iCLOCKdp. Thus, a CD player
can benefit from the iCLOCK‘s lowest-jitter
clock generation which leads to an audible
sound improvement of the CD player‘s DA
converters!
Before replacing your CD player‘s internal
basic clock, check carefully if the frequency
of 16.9344MHz is the right one for your CD
player!
(setting)
Altogether 36 different audio-related clock rates between 8.0 kHz and
24.576 MHz can be selected individually for each Word Clock output pair.
Also 8 pilot tone clock rates from 24 Hz to 60 Hz are available for synchronizing pilot tone resolvers, timecode generators or film projectors and 5 different high-accurate clock references known from GPS receivers or atomic

DIST
DIST does not provide redundancy for the
AES/EBU outputs. If the external AES/EBU or
S/P-DIF clock source fails, the associated

(setting)
DISTRIBUTION This setting allows for forwarding an input AES3 or S/P-DIF
signal to the selected AES/EBU output pair using a hardware bypass. As no
adjustments can be made in this mode, the other functions and parameters
will be hidden, and the second menu page of the AES/EBU pair will not

of its clock source. This is regardless of whether the deviation is caused by
the source itself or by pull-up/down or varispeed settings. The pull range
includes positive and negative differences of up to ±20.0% of the nominal
clock source rate.

HOLD is not available when the system synchronization function SYNC (see
REF1–3 menu page) is set to CYCLESYNC!
LONEREF (function)
LOCK NEXT REFERENCE The function allows for setting a period of time
that the synthesizer will wait after a clock-source failure before automatically selecting the next source according to the REF1–3 settings. During this
time, all output signals are still available according to their respective setting. If the failed source returns to operation within the time defined here,
the synthesizer will resynchronize to it. The factory default is 1 MIN.
30SECs, 1MIN, 10MINs, 30MINs, 60MINs (setting)
One of five time settings between 30 seconds and 60 minutes can be selected here.
HOLD (setting)
With this setting, the synthesizer will enter a mode of operation where it
waits until the previously lost clock source returns. The output rate is set
based on the last recognized clock rate.
LOTIME (function)
LOCK TIME The Lock Time function sets a period required by the synthesizer
to update its clock rate from the previously selected source to a subsequently selected source. The factory default is 5 SECs.
5SECs, 30SECs, 1MIN, 10MINs, 30MINs (setting)
One of five time settings between 5 seconds and 30 minutes for updating
rate differences between the original and a subsequently selected clock
source can be selected here.

PRESET
The preset management enables to store eight different set-ups of all function settings which have been set within the whole iCLOCK system menu, as
so-called ‚Presets‘. When switching over the presets, all individual function
settings will be switched at one time. Additionally, the preset management
stores intermediately the whole current system status permanently in a socalled ‚System-Preset‘. This system-preset works fail-safe, which provides an
automatic function-setting-recovery after, e.g., a mains failure!
!
Software Reset
If a software-reset has been executed with help of the RESET function
on GLOBAL 2/4 page, all presets will be
deleted and the factory default settings are
loaded again.
When switching on your iCLOCK or iCOCKdp for the first time, all presets
contain of the same factory default settings as described in the previous
chapters of this manual. This system condition is equal to this one after a
software-reset.
After normal switching on the unit, the last system status stored in the
system-preset will be loaded. If this is different compared to the settings of
the last active preset, the selected setting under the function OPERATION
will be marked with a (*). If you want to work with the current system status, you have to store it in one of the eight available presets. If you prefer
to work with that preset, which was active before last switching off / on the
unit, you have to load this preset separately.
But if the GPIO preset control is active, your iCLOCK or iCLOCKdp starts
using the preset which was previously active, no matter if the system-preset
consists of different settings, which are due to changes before switching of
the unit.

iCLOCK TECHNOLOGY
Functional Principle
iCLOCK‘s principle operation is completely different to conventional
products. The customer, as a matter of priority, defines the clock rates and
formates which are constantly available at the outputs – not depending on
the incoming reference signals! Limitations regarding defined combinations
of input and output clock signals do not exist for iCLOCK. All inputs and
outputs can be routed and combined freely.
Example
Input Reference Change
44.1kHz to 48.0kHz
Output WCLK
192.0kHz
iCLOCK is synchronized by an external Word
Clock reference with 44.1kHz. The outputs
are adjusted to different clock rates (see
adjacent diagramm). If the external reference
changes to 48.0kHz, the predefined outgoing
clock rates will remain unchanged!
Output WCLK
176.4kHz
Output WCLK
32.0kHz
Output WCLK
44.1kHz
Output WCLK
48.0kHz
The reason is that iCLOCK‘s intelligent synthesis
process synchronizes every reference signal
phase-locked and converts it simultaneously
into the adjusted output clock rates. Thus the
typical signal distribution effect, »a change
of input clock rate changes all output clock
rates«, is prevented in general. The adjusted
output clock rates are permanently available,
not depending on the frequency or format of
the incoming reference!
Functional principle during input reference change
Furthermore, unlike standard clock generators, iCLOCK‘s unique concept
enables to set all system functions during any operation mode. This is
regardless of whether the synthesizer is synchronized internally or by an
external source. Doing this, the powerful synthesis process enables additionally, as an outstanding feature, the use of the pull up/down and varispeed
functions simultaneously! Thus any conceivable adaption of the outgoing
basic clock rates is possible with iCLOCK.
During this process the system detects automatically useful phase relationships between the reference input and generated output signals. Adjustments aligned to AES11-1997/2003 and EBU R83-1996 will be executed in
realtime independently.
SoftReLock
SoftReLock is a special system routine executed by the synthesizer in every
operation mode of reference change or reference resynchronization.
Especially in cases of the later described SEQSYNC or CYCLESYNC functions,
SoftReLock guarantees a gradual and seamless synchronization update of
the internal signal generators, or all iCLOCK output signals respectively,
to the basic clock rate of a new or reestablished reference source. Also if
complete different reference types of unequal sources are synchronized
in succession, e.g. NTSC video after pulled down 48.0kHz AES11, the
SoftReLock routine ensures interruption-free and gently adjustment of
iCLOCK‘s output signals to the new reference.
SoftReLock represents one of the most important functions to support
the system‘s ability providing continous clock supply under all imaginable
operation modes.

Sequence Synchronization
Example
If the first source (REF1) has failed, the synthesizer tries automatically to synchronize
the next source (REF2). When no reference
is available the system waits until the timing
interval of the LONEREF function (A) has
elapsed to synchronize the next reference. Is
a clock source present, the synthesizer starts
to synchronize this under consideration of
the LOCKTIME timing interval (B). If this
reference also fails the system checks for the
third source (REF3) in same procedure.
Note!
If a reference slot is set to »NO REF« the system skips this slot and synchronizes the next
activated slot or the internal video reference
generator.
The system will be locked as long as a clock
source is available at the respective reference slot. But after synchronizing the next
further reference it will not try to resynchronize the previous one if this has returned. If
no utilizable signal is present on the three
slots, the synthesizer will synchronize the internal video reference generator as the final
clock source. After this a returned external
source will be not synchronized any more.
Sequence Synchronization (SEQSYNC) represents the default setting when
activating the REF1–3 menu page. It indicates the standard reference
synchronization function of iCLOCK. The timing of this process is aligned
to the parameter adjustments of the LONEREF (Lock Next Reference) and
LOCKTIME (Lock Time) functions (see GLOBAL 2/4 page).

Sequence Synchronization with three external references
Cycle Synchronization
Example
With Cycle Synchronization (CYCLESYNC) iCLOCK supports an outstanding
feature for automated synchronization of different external clock sources.
If the first source (REF1) has failed, the synthesizer tries to synchronize the next source
(REF2) after passing the LONEREF timing
interval (A). When a second source is available
and synchronized finally (after passing the
LOCKTIME timing interval, B), 10 seconds later
the system starts querying REF1 for source
reestablishment again. If the system finds a
utilizable source signal within the defined
LONEREF period, it will resynchronize to the
REF1 signal.
When no reference is available at REF2 the
system waits until the timing interval of the
LONEREF function (A) has elapsed and starts
to check REF3 for a clock source. If REF3 is set
to »NO REF« the system skips this reference
slot and synchronizes the internal video reference generator under consideration of the
LOCKTIME timing interval (B).

iC-ALARM up to operating system V2.10
The optional iC-ALARM interface (ordering no. 8005-065) is only suitable
for iCLOCK software versions up to V2.10. From V2.11 you must (!) use the
iC-ALARM/GPI interface, see below.
The iC-ALARM interface enables to trans-fer signals depending on three
different critical operating conditions. Each of the potential-free alarm
outputs is directly coupled to a floating change-over relay and is designed
as an individual pin of the 15pins high-density
D-Sub connector. Thus all three alarm signals can be transfered simultaneously. The relays change their states instantly when the following
operating conditions are present:
ALARM OUT 1: Loss of clock reference at the currently active input
ALARM OUT 2: Loss of Main1 or Main2 (or circuit), only iCLOCK dp
ALARM OUT 3: Loss of the internal reference oscillator
Every of the above mentioned operating conditions activate also the red
front panel LED »ALARM set«.
The relays are normalled when the described operating conditions work
faultlessly. If a disturbance occurs, the according relay faills instantly.
The output contacts supply a max. switching power of 30 W with
30 V / 1A DC / AC peak. The type of the used relays is called TQ2-5V from
NAIS / Matsushita (http://www.nais-e.com/relay/index.html).

iC-ALARM/GPI from operating system V2.11 or higher
The optional iC-ALARM/GPI interface (ordering no. 8005-066) is only
suitable for iCLOCK software version V2.11 or higher.
The iC-ALARM/GPI interface offers same basis functionality like the
previously described iC-ALARM. New to the iC-ALARM/GPI interface is its
GPIO function (see page 31).
General Function Description
The iC-ALARM/GPI interface enables to transfer signals depending on three
different critical operating conditions. Each of the potential-free alarm
outputs can be individually set as closing or opening contact by using
different jumper settings on the interface‘s PCB. Furthermore, every output
is directly coupled to a floating change-over relay and is designed as an
individual pin of the 15pins high-density D-Sub connector. Thus, all three
alarm signals can be transfered simultaneously. The relays change their
states instantly when the following operating conditions are present:
ALARM OUT 1: Loss of clock reference at the currently active input
ALARM OUT 2: Loss of Main1 or Main2 (or circuit), only iCLOCKdp
ALARM OUT 3: Loss of the internal reference oscillator
Every of the above mentioned operating conditions activate also the red
front panel LED »ALARM set«.
The relays are normalled when the described operating conditions work
faultlessly. If a disturbance occurs, the according relay faills instantly.
The output contacts supply a max. switching power of 30 W with
30 V / 1A DC / AC peak. The type of the used relays is called TQ2-5V from
NAIS / Matsushita (http://www.nais-e.com/relay/index.html).
Furthermore, when running system V2.11 or higher in your iCLOCK
or iCLOCKdp, you can take advantage of the interface‘s new GPIO
functionality. This enables to switch over the 8 user presets from remote
work spaces or central control rooms.
Features
Three independent potential-free alarm outputs simultaneously

The above mentioned HD tri-level standards and frame rates
can be converted into NTSC standard definition 29.97Hz when
the internal video reference generator‘s format is set to »NTSC«.
The above mentioned HD tri-level standards and frame rates
can be converted into PAL standard definition 25Hz when the
internal video reference generator‘s format is set to »PAL«.
When locking your iCLOCK or iCLOCKdp to HD tri-level
references, their individual frame rates can not be displayed
correctly under »STATUS«, as it is the case when locking SD
bi-level references. This is due to system reasons. But your
iCLOCK will be locked as it should be.

When iCLOCK is shipped, the two BNC-based
video output pairs are transfering the video
signal of the internal video reference generator
simultaneously. Two Jumpers are put on two
2-pin sockets, J16 and J17.
Removing the jumpers from the 2-pin sockets
will split up the dual video BNC output connectors for two video generators as follows.
VIDEO OUT 1 = internal video reference
