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 75Ωtransmission 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
800mV
p-p
to 1V
p-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.
