CLC001

Serial Digital Cable Driver with Adjustable Outputs

General Description

The CLC001 is a monolithic, high-speed cable driver de-

signed for use in SMPTE 259M serial digital video and ITU-T

G.703 serial digital data transmission applications. The

CLC001 drives 75

Ω transmission lines (Belden 8281 or

equivalent) at data rates up to 622 Mbps. Controlled output

rise and fall times (400 ps typical) minimize transition-

induced jitter. The output voltage swing is adjustable from

800 mV

p-p to 1.0 Vp-p using an external resistor.

The CLC001’s output 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 trans-

mission applications.

The CLC001 is powered from a single +3.3V supply and

comes in a small 8-pin SOIC package.
