FEATURES
DESCRIPTION
The LMH0202 Dual SMPTE 292M / 259M serial
digital cable driver is a monolithic, high-speed cable
driver designed for use in SMPTE 292M / 259M serial
digital video and ITU-T G.703 serial digital data
transmission applications. The LMH0202 drives 75Ω
transmission lines (Belden 8281, Belden 1694A or
equivalent) at data rates up to 1.485 Gbps.

Data Rates to 1.485 Gbps
Dual Differential Inputs
Dual 75Ω Differential Outputs
Two Selectable Slew Rates
The LMH0202 provides two selectable slew rates for
SMPTE 259M and SMPTE 292M compliance. The
output voltage swing is adjustable via a single
external resistor.
Adjustable Output Amplitude
Single 3.3V Supply Operation
Commercial Temperature Range: 0°C to +70°C
Typical Power Consumption: 250 mW in SD
Mode and 300 mW in HD Mode
The LMH0202 offers the flexibility to implement either
dual differential inputs or a single differential input
(externally routed via PCB) to dual differential
outputs. The latter option provides an ideal solution
for DVB-ASI applications where only the non-inverted
outputs are typically used.
APPLICATIONS

SMPTE 292M, SMPTE 344M, and SMPTE 259M
Serial Digital Interfaces
The LMH0202 is powered from a single 3.3V supply.
Power consumption is typically 250 mW in SD mode
and 300 mW in HD mode.

DEVICE OPERATION
INPUT INTERFACING
The LMH0202 accepts either differential or single-ended input. The inputs are self-biased, allowing for simple AC
or DC coupling. DC-coupled inputs must be kept within the specified common-mode range. SDI and SDI are self-
biased at approximately 2.1V with VCC = 3.3V. Figure 2 shows the differential input stage for SDI and SDI.

DVB-ASI APPLICATIONS
The dual differential inputs of the LMH0202 may be externally routed to a single differential input as shown in
Figure 3. This provides a solution for DVB-ASI applications where two non-inverted outputs are needed.

OUTPUT INTERFACING
The LMH0202 uses current mode outputs. Single-ended output levels are 800 mVP-P into 75Ω AC-coupled
coaxial cable (with RREF = 750Ω). Output level is controlled by the value of the resistor connected between the
RREF pin and VCC
.
The RREF resistor should be placed as close as possible to the RREF pin. In addition, the copper in the plane
layers below the RREF network should be removed to minimize parasitic capacitance.
OUTPUT SLEW RATE CONTROL
The LMH0202 output rise and fall times are selectable for either SMPTE 259M or SMPTE 292M compliance via
the SD/HD pin. For slower rise and fall times, or SMPTE 259M compliance, SD/HD is set high. For faster rise
and fall times, or SMPTE 292M compliance, SD/HD is set low.

(1) 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.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(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 finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
