CLC006

CLC006 Serial Digital Cable Driver with Adjustable Outputs August 1998 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 75Ω 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 backmatched and terminated 75Ω cable. Output swing is adjustable from 0.7 Vp-p to 2 Vp-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 mVp-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.
