CLC001 Serial Digital Cable Driver with Adjustable Outputs

March 2001

General Description

The CLC001 is a monolithic, high-speed cable driver
designed for use in SMPTE 259M serial digital video and
ITU-T G.703 serial digital data transmission applications.
The CLC001 drives 75Ω transmission lines (Belden 8281 or
equivalent) at data rates up to 622 Mbps. Controlled output
rise and fall times (400 ps typical) minimize transition­induced jitter. The output voltage swing is adjustable from
800 mV

The CLC001’soutput stage consumes less power than other
designs. The differential inputs accept LVDS signal levels,
LVPECL levels directly or PECL with attenuation networks.

All these make the CLC001 an excellent general purpose
high speed driver for high-speed, long distance data
transmission applications.

The CLC001 is powered from a single +3.3V supply and
comes in a small 8-pin SOIC package.
