CLC007

Serial Digital Cable Driver with Dual Complementary

Outputs

General Description

National’s Comlinear CLC007 is a monolithic, high-speed

cable driver designed for the SMPTE 259M serial digital

video data transmission standard. The CLC007 drives 75

Ω

transmission lines (Belden 8281 or equivalent) at data rates

up to 400 Mbps. Controlled output rise and fall times (650 ps

typical) minimize transition-induced jitter. The output voltage

swing, typically 1.65V, set by an accurate, low-drift internal

bandgap reference, delivers an 800 mV swing to back-

matched and terminated 75

Ω cable.

The CLC007’s class AB output stage consumes less power

than other designs, 195 mW with all outputs terminated, and

requires no external bias resistors. The differential inputs ac-

cept a wide range of digital signals from 200 mV

levels within the specified common-mode limits. All this

make the CLC007 an excellent general purpose high speed

driver for digital applications.

The CLC007 is powered from a single +5V or −5.2V supply

and comes in an 8-pin SOIC package.
