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
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
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.
