CLC006
Serial Digital Cable Driver with Adjustable Outputs
General Description
National’s Comlinear CLC006 is a monolithic, high-speed ca-
ble driver designed for the SMPTE 259M serial digital video
data transmission standard. The CLC006 drives 75Ω trans-
mission lines (Belden 8281 or equivalent) at data rates up to
400 Mbps. Controlled output rise and fall times (650 ps typi-
cal) 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 75Ω cable. Output swing is ad-
justable from 0.7 V_P-P to 2 V_P-P using external resistors.
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 inputs
accept a wide range of digital signals from 200 mV_P-P to 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.
