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.
