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 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.

NOTE: All resistors in Ohms, capacitors in Farads,

and inductors in Henrys, unless otherwise stated.

* Typical value: varies with layout, and represents a trade-off

between good eye shape and output return loss.

5n6 is the optimum value for an 800mV output swing

and 3.3V operation.

4n7 is the optimum value for an 800mV output swing and

2.5V operation.

6n8 is the optimum value for an 1200mV output swing.
