LMH0202
Dual SMPTE 292M / 259M Serial Digital Cable Driver
General Description
The LMH0202 Dual 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
LMH0202 drives 75Ω transmission lines (Belden 8281,
Belden 1694A or equivalent) at data rates up to 1.485 Gbps.
The LMH0202 provides two selectable slew rates for
SMPTE 259M and SMPTE 292M compliance. The output
voltage swing is adjustable via a single external resistor.
The LMH0202 offers the flexibility to implement either dual
differential inputs or a single differential input (externally
routed via PCB) to dual differential outputs. The latter option
provides an ideal solution for DVB-ASI applications where
only the non-inverted outputs are typically used.
The LMH0202 is powered from a single 3.3V supply. Power
consumption is typically 250mW in SD mode and 298mW in
HD mode.
