AV vational Semiconductor CLC005 ITU-T G.703 Cable Driver with Adjustable Outputs General Description Nationals Comlinear CLCO0O5 is a monolithic, high-speed cable driver designed for the ITU-T G.703 serial digital data transmission standard. The CL.C005 drives 75Q transmis- sion lines (Belden 8281 or equivalent) at data rates from DC to over 622 Mbps. Output signal waveforms produced by the CLCO005 comply with G.703 specifications. Controlled output rise and fall times (650 ps typical) minimize trahsition- 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 75Q cable. Out- put swing is adjustable from 0.7 V,,,, to 2.2 V,. using exter- nai 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 in- puts accept a wide range of digital signals from 200 mV,,,, to G.703 levels within the specified common-made limits. All this make the CLCO05 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.
