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 125mW in SD mode and 149mW in
HD mode.
