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.
