DESCRIPTION
The LMH0002 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 LMH0002 drives 75Ω
transmission lines (Belden 8281, Belden 1694A or
equivalent) at data rates up to 1.485 Gbps.
The LMH0002 provides two selectable slew rates for
SMPTE 259M and SMPTE 292M compliance. The
output voltage swing is adjustable via a single
external resistor.
The LMH0002 is powered from a single 3.3V supply.
Power consumption is typically 125 mW in SD mode
and 149 mW in HD mode. The LMH0002 is available
in an 8-pin SOIC or 16-pin WQFN package.

APPLICATION INFORMATION
Device Operation
INPUT INTERFACING
The LMH0002 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 selfbiased at approximately 2.1V with VCC = 3.3V. Figure 3 shows the differential input stage for SDI and SDI.

Figure 3. Differential Input Stage for SDI and SDI.
OUTPUT INTERFACING
The LMH0002 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 RREF 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 LMH0002 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.
REPLACING THE GENNUM GS1528, GS1528A, and GS1578A
The LMH0002MA is form-fit-function compatible with the Gennum GS1528 and GS1528A. The LMH0002SQ is
form-fit-function compatible with the Gennum GS1578A.

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
