Security Protocol License with Security-Hardened NTP Reflector™/Firewall
Some applications require security enhancements above and beyond what might
otherwise be acceptable. For this reason, the SyncServer S600/S650 can be
seriously hardened from both the NTP operational perspective and the authentication
perspective.
Operational Hardening
The security protocol license includes the security-hardened NTP Reflector with
hardware firewall functionality. The GbE line speed NTP Reflector with 100%
hardware-based NTP packet processing can handle in excess of 360,000 NTP
requests per second (mode three NTP client packets only). This same hardware
also acts as a CPU-protecting firewall by bandwidth limiting all non-NTP traffic. In
addition to the NTP Reflector, there are denial-of-service (DoS) functions monitoring
the packet flow. Abnormally high NTP or non-NTP traffic initiates an SNMP trap. In
a DoS attack, the S600/S650 remains impervious to the level of network traffic that
could be delivered as all packets are processed in hardware at line speed, though
legitimate NTP client requests for time may be blocked elsewhere in the network due
to the increased DoS flow.
Authentication Hardening
Authentication—whether client, server, or user access—is the next level in security
hardening. The NTP Autokey functionality is a step up from MD5 when it is required
to have the next level of NTP client-to-server authentication. For user authentication/
permission to access the web interface, TACACS+, RADIUS, LDAP, and CA-signed
X.509 certificates are also included in the security protocol license.

Multi-Port/Profile IEEE 1588 PTP Output
License
The IEEE 1588 PTP output license enables PTP grandmaster
operations leveraging the built-in hardware timestamping in all
SyncServers. LAN 2, 3, and 4 as well as the optional
10 GbE LAN 5 and 6 can each be uniquely configured as
PTP grandmasters with this single-option license. This is a
very cost-effective way to scale PTP grandmaster operations
and increase configuration flexibility.
PTP profiles supported include the Enterprise Profile, default
profile, and Telecom Profile. These profiles can be configured
in any combination, the limitation being one profile per
port. The Enterprise Profile in a grandmaster is an official
recognition of the default multicast profile and the use of
unicast delay_request messages (often referred to as hybrid
mode). PTP multicast slave capacity ranges from 360,000
slaves at 1 delay_request/second rate down to 2,800 slaves
at 128 delay_request/second rate. PTP telecom profile slave
capacity is up to 800 slaves at 128 packets per second.
Overall capacity of the Syncserver is 360,000 time stamps/
second allocated by the configuration of the protocol and
profile on each port.

IEEE 1588 PTP Input License
PTP as a timing input is useful for several different application
scenarios of which one is tunneling time through PTP over
the network to an S600/S650 with no GNSS connection.
PTP input can also be used as a backup time reference
in the event of the loss of the GNSS signal. When used
as a back up to GNSS, the S600/S650 is equipped with
Automatic Asymmetry Compensation that automatically
measures, calibrates, and stores up to 32 different network
path delay asymmetries observed between the PTP slave
S600 and the PTP grandmaster. In the event of the loss of
the GNSS signal, the S600 recognizes the current network
path and automatically applies the correct asymmetric path
compensation to keep the S600 tightly synchronized to
the remote PTP grandmaster. If the network path between
the S600 slave and the grandmaster changes, the applied
compensation will also change.

The S600/S650 10 GbE option adds two SFP+ ports equipped
with hardware timestamping that supports NTP, PTP, and NTP
Reflector operations. The 10 GbE ports are in addition to the
standard four 1 GbE ports for a total of 6 ports. These ports are
ideal for interoperability with 10 GbE switches. SFP modules
supported are limited to 10 GbE speeds only, and overall system
time stamping capacity remains as specified. The 10 GbE SFP+

Rubidium Atomic Oscillator
The rubidium atomic clock oscillator upgrade improves not
only the stability and ongoing accuracy of the SyncServer, but
also its holdover accuracy, saving valuable time for the user.
The standard SyncServer is equipped with a crystal oscillator
that keeps the clock accurate to specifications while tracking
GNSS. However, if the GNSS signal is lost, thereby placing
the unit in holdover, the standard oscillator soon drifts away
from perfect. Upgrading the oscillator significantly improves
the clock accuracy during holdover.
Rubidium holdover accuracy is <1 μs for the first 24 hours
and <3 μs after the first three days. The advantage of the
rubidium oscillator is that if the GNSS signal is lost, the
SyncServer continues to serve accurate time and maintain
a high level of clock stability. This allows support personnel
plenty of time to correct the GNSS signal problem with little
degradation or disruption in time synchronization accuracy.
Dual AC Power Supplies
The dual-corded, dual-power supply option provides several
levels of time service protection. The power supplies load
share equally, and there is an active power management
system constantly monitoring the operation. If the power to
one cord/circuit is lost or if one power supply fails, the entire
load is instantly picked up by the remaining energized power
supply with no interruption in time services to the network.
Connecting both power supplies to the same circuit provides
protection against a single power supply failure. In the event
of a power supply failure, notification is instantly provided
to the network operator through SNMP trap or email. For
extra level of assurance, the power cord(s) supplied with
the SyncServers have locking rear IEC 60320 connectors to
avoid accidental decoupling.
Dual DC Power Supplies
Oven-Controlled Crystal Oscillator (OCXO)
Similar in application to the rubidium oscillator upgrade, the
oven-controlled crystal oscillator (OCXO) upgrade improves
the holdover accuracy beyond the standard oscillator, though
not nearly as much as the rubidium oscillator. OCXO holdover
accuracy is 25 μs for the first day. Depending on the level and
duration of accuracy needed, the OCXO is a compromise
between the standard oscillator and the rubidium oscillator.

circuit provides protection against a single power supply
failure. In the event of a power supply failure, notification is
instantly provided to the network operator through SNMP
trap or email. The option includes two locking connectors and
6 pins to allow the user to make a power cable.

S650 Timing I/O Module
The Timing I/O module is an exceedingly versatile time
and frequency input and output option. In the standard
configuration, it supports the most popular input and output
time codes, sine waves, and rates. The following illustration
shows the standard configuration and the configuration with
the FlexPort option.
The standard configuration offers a broad yet fixed selection
of signal I/O. J1 is dedicated to time code and rate inputs, J2
to sine wave inputs, and J3-J8 to mixed signal outputs. The
standard Timing I/O module configuration is 1PPS or IRIG
B AM-In, 10 MHz-In, IRIG AM and IRIG DCLS-Out, 1PPSOut, and 10 MHz-Out. (See the following page for Timing I/O
Module specifications.)
FlexPort™ License for Timing I/O Modules
Microsemi’s unique FlexPort technology efficiently and
cost-effectively adds innovative “any signal, any connector”
technology, eliminating the wasted space inherent with
legacy-style, fixed-signal modules/BNCs.
The FlexPort technology option enables the six output BNCs
(J3–J8) to output any supported signal (time codes, sine
waves, programmable rates, and so on) all configurable in
real time through the secure web interface. Similarly, the
two input BNCs (J1–J2) can support a wide variety of input
signal types. This uniquely flexible BNC-by-BNC configuration
makes efficient and cost-effective use of the 1U space
available.
Two Timing I/O modules double the number of supported
input and output signals. Unlike legacy modules with fixed
count BNCs outputting fixed signal types per module, with
FlexPort technology the user can have up to 12 BNCs (two
Timing I/O modules) outputting any combination of supported
signal types. Fine tuning of rate and time code signal outputs
is possible as each output BNC can be individually phase
adjusted to the nanosecond level to accommodate different
output cable lengths.
This level of timing signal flexibility is unprecedented and
can even eliminate the need for additional signal distribution
chassis as there is no degradation in the precise quality of the
coherent output signals.
FlexPort vs. Standard Configuration
A single FlexPort license enables configuration flexibility on all installed Timing I/O modules.
Note: All Timing I/O modules are factory installed and must be ordered at the time of initial purchase. The FlexPort license can
be added at any time.

Note: Measured on any 10 MHz output.
Note: For applications sensitive to 10 MHz phase noise,
Microsemi recommends the Low Phase Noise modules. The
Tiiming I/O Module 10 MHz outputs are not meant for low phase
noise applications.
1PPS Time Interval Measurement Option
Using the S650 Timing I/O module with the 1PPS Time Interval Measurement option can be very useful to compare the time
between the S650 and another device that outputs a 1PPS signal. Typical application is to measure how accurate a device
can synchronize to the S650 such as a PTP slave device over a network. This measurement is essential in understanding the
detrimental effects of switches and network traffic on the PTP slave’s ability to accurately synchronize to the S650.
Measurements are easy to perform. Merely connect the 1PPS output from the external device to the S650 Timing I/O module J1
BNC and press the start button on the web interface. The external 1PPS accuracy statistics relative to the S650 are computed
and displayed in real-time through the web interface. The current interval, sample count, max, min, mean, standard deviation,
median, and RMS of the measurement set are continuously updated on the web interface throughout the duration of the test.
Measurement resolution is 10 nanoseconds. Tests have durations from 10 minutes to 1 day with results saved locally and can be
exported in text formats easily imported into analysis programs. Measurements can also be sent continuously to a user-defined IP
address and UDP port number, or to the DATA/TIMING serial port.

Multi-GNSS Constellation License
Windows Time Synchronization Software
Timing integrity, continuity, and reliability can be improved
with the multi-GNSS constellation license that adds support
for GLONASS, BeiDou, and SBAS constellations in addition
to the standard GPS constellation. With more satellites in
view, timing performance can be improved in challenging
environments such as urban canyons.
Track GPS/SBAS, GLONASS and/or BeiDou Satellite
Constellations for improved integrity and satellite visibility in
urban canyons
All SyncServer S600 series are equipped with a GNSS
receiver capable of simultaneously tracking more than one
GNSS constellation. The primary constellations include
GPS, GLONASS, and Beidou. In addition, the regional GPS
Satellite Based Augmentation Satellites (WAAS, EGNOS,
and MSAS) are also used. Users select one or two of the
primary constellations to track. If GPS is one of the selected
constellations, then the SBAS satellites are automatically
included in the tracking.
Note: The SyncServer S600 series uses a different antenna
and splitter for GPS/SBAS/GLONASS compared to GPS/
SBAS/GLONASS/BeiDou. See the antenna section of this
datasheet for more details.
Network time synchronization software is an essential part of
distributing time to network clients. Domain Time II software
for Windows is a comprehensive NTP/PTP software solution
that simplifies network time synchronization. Versatile time
clients and software servers keep the network hierarchy
synchronized to the SyncServer. Easy-to-use management
tools simplify and automate many tasks related to keeping the
clients up-to-date. Monitoring functions track synchronization
across the network to notify the administrator of any
problems. The result is a reliable time synchronization system
that requires little management overhead and provides
tremendous value to the integrity of network operations and
applications.

Outdoor Antenna Basics
Antenna cables and accessories enable versatile solutions
that are easy to achieve. Inline GNSS amplifiers installed at
the antenna are an easy way to extend cable runs from
225 feet to up to 900 feet, depending on cable type.
Lightning arrestors provide valuable electrical shock
protection to the SyncServer. Antenna cable splitters leverage
a single antenna and cable for up to four GNSS receivers.
Ordering antenna components is a simple task. The most
important thing the user needs to have is a rough idea of the
total cable length needed between the SyncServer and the
mounting location of the antenna. Any extra cable can be
coiled to the side.
Pre-configured kits that include cable, antenna, and related
mounting accessories are available. These kits vary by total
cable length, and are based on whether a lightning arrestor
is required or not. For long cable runs (>225 feet), the
components are assembled individually.
To assist and simplify configuration, Microsemi has included
an Excel-based antenna configurator on the website. The
configurator helps the user determine the exact part numbers
they need for the desired cable length and accessories.
Important: The antenna kit (part number 093-15202-001)
includes a short SyncServer adapter cable with BNC(m)-N(f)
connectors. All primary antenna cables use N(m) connectors
on either end. A single cable must be used between the
adapter cable and the next accessory (lightning arrestor, inline
amplifier, or antenna). Lightning arrestors include a
25-foot cable to connect to the next accessory (inline
amplifier or antenna).

GPS/GLONASS Antenna
GPS/GLONASS/BeiDou Antenna
The standard antenna used with the SyncServer S600/S650
is a high-gain (40 dB) GNSS antenna covering the GPS L1,
GLONASS L1, and SBAS (WAAS, EGNOS, and MSAS)
frequency band (1575 MHz to 1606 MHz). The antenna has
a three-stage low-noise amplifier, with a mid-section SAW
with a tight pre-filter to protect against saturation by highlevel sub-harmonics and L-Band signals, making it excellent
for timing applications. An L-bracket for pole mounting and
3-foot BNC(m) to N(f) cable is also included.
This wide-band antenna is a precision high-gain GNSS
antenna covering the BeiDou B1, Galileo E1, GPS L1,
GLONASS L1, and SBAS (WAAS, EGNOS, QZSS, and
MSAS) frequency band (1557 MHz to 1606 MHz). It provides
very circular polarized signal reception through the entire
bandwidth of the antenna, thereby providing superior
multipath signal rejection. The antenna has a three-stage low
noise amplifier, comprised of one input LNA per feed, a mid
section SAW to filter the combined output, and a final output
gain stage. An additional pre-filter provides extra strong
protection from near frequency and strong harmonic signals.
An L-bracket for pole mounting and 3-foot BNC(m) to N(f)

GNSS Inline Amplifier
GNSS Lightning Arrestor
Cable length is a common cause for signal loss between
the GNSS antenna and the GNSS receiver. As with any
electromagnetic radio wave, GNSS signals become
attenuated as they pass through an electrical cable. The
amount of signal loss depends on the length and type of
cable used. The inline amplifier attaches the antenna and the
antenna cable. It uses the same power as the antenna and
does not require extra wiring.
Lightning does not have to strike the antenna to significantly
damage the antenna or the GNSS receiver. Damage is often
due to the effects of a lightning strike on a nearby structure,
not a direct strike on the antenna itself. Since lightning strikes
may induce damaging voltages in the antenna system when
striking nearby objects, attempt to locate the antenna away
from lightning rods, towers, and other structures that attract
lightning. Also, locate the GNSS antenna lower than any
nearby structures that are likely to attract a strike.
Features
• Extended cable length up to 900 ft depending on the cable
type
• Fits inline with antenna cable
• No external power source needed
• Simple installation

GPS L1 4:1 Active Splitter
GPS/GLONASS/BeiDou Splitter
The Microsemi Active Splitter allows multiple GPS receivers to
share a single antenna. Designed for both manufacturing and
position/timing redundancy applications, the GPS L1 Active
Splitter provides dependable signals for four GPS receivers.
This L band frequency, RoHS-compliant 4:1 active splitter makes
it possible to use a single GPS referencing antenna and cable
arrangement for multiple synchronization systems. The antenna
DC bias select circuit allows for the active antenna DC input
to be applied to any or all RF outputs. One DC voltage will be
chosen to power the antenna while other inputs will be switched
to DC loads. If the selected DC bias input should fail, the DC
bias will automatically switch to another DC input to ensure an
uninterrupted supply to the active antenna.
Features
• Four ports
• High isolation
Benefits
• Cascades conveniently without adding separate amplifiers and
bias-tees between splitters
• Delivers precise GPS signals over a wide temperature range
and in harsh environmental conditions
• Eliminates feedback and interaction between any GPS system
connected to it.
Features
• Four ports
• GPS/GLONASS/Beidou compatible
Benefits
• Amplified to offset splitter losses
• Standard antenna DC bias select
• Cascades conveniently without adding separate amplifiers and
bias-tees between splitters
