HD-SDI Cable Driver
Not recommended for new designs.
Please use the GS2988 for new designs.
The GS1678 is a high-speed BiCMOS integrated circuit designed to drive one or two 75Ω coaxial cables. The GS1678 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 GS1678 accepts industry-standard differential input levels, including LVPECL and CML. The DISABLE pin powers-down the output driver, leaving the serial data output in a high-impedance state. The GS1678 features an adjustable output swing using an external bias resistor. The single-ended output swing is adjustable from 600mVpp to 1200mVpp. The GS1678 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 GS1678 is footprint and drop-in compatible with existing GS1578A and LMH0002 designs, with no additional application changes required.
