GS1679 Cable Driver with HD/SD Capability The GS1679 is a high-speed BiCMOS integrated circuit designed to drive one to four 75Ω coaxial cables.

The GS1679 can drive data rates up to 1.485Gb/s, and provides two selectable slew rates in order to achieve compliance to SMPTE 292M, SMPTE 259M and SMPTE 344M.

The GS1679 accepts industry-standard differential input levels, including LVPECL and CML.

The DISABLE1 and DISABLE2 pins power-down the first and second output drivers respectively, leaving the

GS1679 Features

* an adjustable output swing using an external bias resistor. The single-ended output swing is adjustable from 600mVpp to 1200mVpp. The GS1679 can be powered from either a 3.3V or a 2.5V supply. Power consumption is typically 110mW using a 2.5V power supply. The GS1679 is forward footprint-compatible
