LMH0002
SMPTE 292M / 259M Serial Digital Cable Driver
General 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 LLP package.
