CLC006

Serial Digital Cable Driver with Adjustable Outputs

General Description

National’s Comlinear CLC006 is a monolithic, high-speed

cable driver designed for the SMPTE 259M serial digital

video data transmission standard. The CLC006 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. Output swing is adjust-

able from 0.7 V

The CLC006’s class AB output stage consumes less power

than other designs, 185 mW with both outputs terminated,

and requires no external bias resistors. The differential in-

puts accept a wide range of digital signals from 200 mV

ECL levels within the specified common-mode limits. All this

make the CLC006 an excellent general purpose high speed

driver for digital applications.

The CLC006 is powered from a single +5V or −5.2V supply

and comes in an 8-pin SOIC package.
