DEVICE DESCRIPTION
The LMH0026 SD SDI Reclocker is used in many types of digital video signal processing equipment. The
LMH0026 supports the SMPTE 259M (C) serial digital video standard, with a corresponding serial data rate of
270 Mbps. DVB-ASI data at 270 Mbps may also be retimed. The LMH0026 retimes the serial data stream to
suppress accumulated jitter. It provides two low-jitter, differential, serial data outputs. The second output may be
selected to output either serial data or a low-jitter serial data-rate clock. Controls and indicators are: serial datarate clock or second serial data output select, SD indicator output, lock detect output, auto/manual data bypass,
and output mute.
Serial data inputs are CML and LVPECL compatible. Serial data and data-rate clock outputs are differential CML
and produce LVPECL compatible levels. The output buffer design can drive AC or DC-coupled, terminated 100Ω
differential loads. The differential output level is 800 mVP-P ±10% into 100Ω AC or DC-coupled differential loads.
Logic inputs and outputs are LVCMOS compatible.
The device package is an HTSSOP-20 with an exposed die attach pad. The exposed die attach pad is
electrically connected to device ground (VEE) and is the negative electrical terminal for the device. This terminal
must be connected to the negative power supply or circuit ground.
Serial Data Inputs, Serial Data and Clock Outputs
SERIAL DATA INPUT AND OUTPUTS
The differential serial data input, SDI, accepts 270 Mbps serial digital video data. The serial data input is
differential LVPECL compatible. The input is intended to be DC interfaced to devices such as the LMH0074
adaptive cable equalizer. The input is not internally terminated or biased. The input may be AC-coupled if a
suitable input bias voltage is provided. Figure 2 shows the equivalent input circuit for SDI and SDI.
The LMH0026 has two, retimed, differential, serial data outputs, SDO and SCO/SDO2. These outputs provide
low jitter, differential, retimed data to devices such as the LMH0001 or LMH0002 cable driver. Output SCO/SDO2
is multiplexed and can provide either a second serial data output or a serial data-rate clock output. Figure 3
shows the equivalent output circuit for SDO, SDO, SCO/SDO2, and SCO/SDO2.
The SCO_EN input controls the operating mode for the SCO/SDO2 output. When the SCO_EN input is high the
SCO/SDO2 output provides a serial data-rate clock. When SCO_EN is low, the SCO/SDO2 output provides
retimed serial data.
Both differential serial data outputs, SDO and SCO/SDO2, are muted when the OUTPUT MUTE input is a logic
low level. SCO/SDO2 also mutes when the Bypass mode is activated when this output is operating as the serial
clock output. When muted, SDO and SDO (or SDO2 and SDO2) will assume opposite differential output levels.
The CML serial data outputs are differential LVPECL compatible. These outputs have internal 50Ω pull-ups and
are suitable for driving AC or DC-coupled, 100Ω center-tapped, AC grounded or 100Ω un-center-tapped,
differentially terminated networks.

SERIAL DATA CLOCK/SERIAL DATA 2 OUTPUT
The Serial Data Clock/Serial Data 2 Output is controlled by the SCO_EN input and provides either a second
retimed serial data output or a low jitter differential clock output appropriate to the serial data rate being
processed. When operating as a serial clock output, the rising edge of the clock will be positioned within the
corresponding serial data bit interval within 10% of the center of the data interval.
Differential output SCO/SDO2 functions as the second serial data output when the SCO_EN input is a logic-low
level. This output functions as the serial data-rate clock output when the SCO_EN input is a logic-high level. The
SCO_EN input has an internal pull-down device and the default state of SCO_EN is low (serial data output 2
enabled). SCO/SDO2 is muted when the OUTPUT MUTE input is a logic low level. When the Bypass mode is
activated and this output is functioning as a serial clock output, the output will also be muted. If an unsupported
data rate is used while in Auto Bypass mode with this output functioning as a serial clock output, the output is
invalid.
Control Inputs and Indicator Outputs
LOCK DETECT
The Lock Detect (LD) output, when high, indicates that data is being received and the PLL is locked. LD may be
connected to the OUTPUT MUTE input to mute the data and clock outputs when no data signal is being
received. Note that when the Bypass/Auto Bypass input is set high, Lock Detect will remain low. See Table 1.
OUTPUT MUTE
The OUTPUT MUTE input, when low, mutes the serial data and clock outputs. It may be connected to Lock
Detect or externally driven to mute or un-mute the outputs. If OUTPUT MUTE is connected to LD, then the data
and clock outputs are muted when the PLL is not locked. This function overrides the Bypass function: see
Table 1. OUTPUT MUTE has an internal pull-up device to enable the output by default.
BYPASS/AUTO BYPASS
The Bypass/Auto Bypass input, when high, forces the device to output the data without reclocking it. When this
input is low, the device automatically bypasses the reclocking function when the device is in an unlocked
condition or the detected data rate is a rate which the device does not support. Note that when the Bypass/Auto
Bypass input is set high, Lock Detect will remain low. See Table 1. BYPASS/AUTO BYPASS has an internal pulldown device.

SD
The SD output indicates that the LMH0026 is locked and processing SD data rates. It may be used to control
another device such as the LMH0002 cable driver. When this output is high it indicates that the data rate is 270
Mbps. The SD output is a registered function and is only valid when the PLL is locked and the Lock Detect
output is high. When the PLL is not locked (the Lock Detect output is low), the SD output defaults to low. The SD
output is undefined for a short time after lock detect assertion or de-assertion due to a data change on SDI. See
Figure 4 for a timing diagram showing the relationship between SDI, Lock Detect, and SD.

SCO_EN
Input SCO_EN enables the SCO/SDO2 differential output to function either as a serial data-rate clock or second
serial data output. SCO/SDO2 functions as a serial data-rate clock when SCO_EN is high. This pin has an
internal pull-down device. The default state (low) enables the SCO/SDO2 output as a second serial data output.
CRYSTAL OR EXTERNAL CLOCK REFERENCE
The LMH0026 uses a 27 MHz crystal or external clock signal as a timing reference input. A 27 MHz parallel
resonant crystal and load network may be connected to the XTAL IN/EXT CLK and XTAL OUT pins.
Alternatively, a 27 MHz LVCMOS compatible clock signal may be input to XTAL IN/EXT CLK. Parameters for a
suitable crystal are given in Table 2.

SNLS253B – MARCH 2008 – REVISED APRIL 2013

The LMH0026 inputs are LVPECL compatible. The LMH0026 has a wide input common mode range and in most
cases the input should be DC coupled. For DC coupling, the inputs must be kept within the common mode range
specified in DC ELECTRICAL CHARACTERISTICS. Figure 5 shows an example of a DC coupled interface
between the LMH0074 cable equalizer and the LMH0026. The LMH0074 output common mode voltage and
voltage swing are within the range of the input common mode voltage and voltage swing of the LMH0026. All
that is required is a 100Ω differential termination as shown. The resistor should be placed as close to the
LMH0026 input as possible. If desired, this network may be terminated with two 50Ω resisters and a center tap
capacitor to ground in place of the single 100Ω resistor.
The LMH0026 outputs are LVPECL compatible. SDO is the primary data output and SCO/SDO2 is a second
output that may be set as the serial clock or a second data output. Both outputs are always active. The LMH0026
output should be DC coupled to the input of the receiving device as long as the common mode ranges of both
devices are compatible. Figure 5 shows an example of a DC coupled interface between the LMH0026 and
LMH0001 cable driver. All that is required is a 100Ω differential termination as shown. The resistor should be
placed as close to the LMH0001 input as possible. If desired, this network may be terminated with two 50Ω
resisters and a center tap capacitor to ground in place of the single 100Ω resistor.
The external loop filter capacitor (between LF1 and LF2) should be 56 nF. This is the only supported value; the
loop filter capacitor should not be changed.
BYPASS/AUTO BYPASS has an internal pulldown to enable Auto Bypass mode by default. This pin may be
pulled high to force the LMH0026 to bypass all data.
OUTPUT MUTE has an internal pullup to enable the outputs by default. This pin may be pulled low to mute the
outputs.
The XTAL IN/EXT CLK and XTAL OUT pins are shown with a 27 MHz crystal and the proper loading. The crystal
should match the parameters described in Table 2. Alternately, a 27MHz LVCMOS compatible clock signal may
be input to XTAL IN/EXT CLK.
The active high LOCK DETECT output provides an indication that proper data is being received and the PLL is
locked.
The SD output may be used to drive the SD/HD pin of an SDI cable driver (such as the LMH0002) in order to
properly set the cable driver’s edge rate for SMPTE compliance. It defaults to low when the LMH0026 is not
locked.
SCO_EN has an internal pulldown to set the second output (SCO/SDO2) to output data. This pin may be pulled
high to set the second output as a serial clock.
The ground connection for the LMH0026 is through the large exposed DAP. The DAP must be connected to
ground for proper operation of the LMH0026.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3)
MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4)
There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
