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 250 mW in SD mode
and 300 mW in HD mode.
