Gennum GS1679
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.FEATURES
