CLC005  Product Folder

National's Comlinear CLC005 is a monolithic, high-speed cable driver designed for the ITU-T G.703 serial digital data transmission standard. The CLC005 drives 75Ohm transmission lines (Belden 8281 or equivalent) at data rates from DC to over 622 Mbps. Output signal waveforms produced by the CLC005 comply with G.703 specifications. Controlled output rise and fall times (650 ps typical) minimize transition-induced jitter. The output voltage swing, typically 2.0V, set by an accurate, low-drift internal bandgap reference, delivers a 1.0V swing to back-matched and terminated 75Ohm cable. Output swing is adjustable from 0.7 V_p-p to 2.2 V_p-p using external resistors.

The CLC005'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 G.703 levels within the specified common-mode limits. All this make the CLC005 an excellent general purpose high speed driver for digital applications.

The CLC005 is powered from a single +5V or -5.2V supply and comes in an 8-pin SOIC package.
