HD-SDI Dual-output Cable Driver
Not recommended for new designs.
Please use the GS2989 for new designs.
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 1.485Gbps, 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 the Gennum® 3G GS2989, allowing for an easier migration of HD designs to 3G.
