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.
