Semtech GS1679

Multi-rate Dual Slew-rate Cable Driver for HD-SDI, SD-SDI & DVB-ASI

Add to Watch List

The GS1679 is a high-speed BiCMOS integrated circuit designed to drive one to four 75? 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 serial data output in a high-impedance state. 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 with Gennum's 3G GS2989, allowing for an easier migration of HD designs to 3G.
