CLC002

SMPTE 292M / 259M Serial Digital Cable Driver

General Description

The CLC002 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 CLC002

drives 75

Ω transmission lines (Belden 8281, Belden 1694A

or equivalent) at data rates up to 1.485 Gbps.

The CLC002 provides two selectable slew rates for SMPTE

259M and SMPTE 292M compliance. The output voltage

swing is adjustable from 800 mV

external resistor.
