Description

The GS1528A/9068A is a second generation, high speed

BiCMOS integrated circuit designed to drive one or two

75W coaxial cables.

The GS1528A may drive data rates up to 1.485Gb/s and

provides two selectable slew rates in order to achieve

compliance to SMPTE 259M, SMPTE 344M and SMPTE

292M.

The GS9068A may drive data rates up to 540Mb/s and will

achieve compliance to SMPTE 259M and SMPTE 344M.

The GS1528A/9068A accepts a LVPECL level differential

input that may be AC coupled. External biasing resistors at

the inputs are not required. Power consumption is typically

168mW using a 3.3V power supply. The GS1528A/9068A is

Pb-free, and the encapsulation compound does not contain

halogenated flame retardant. This component and all

homogeneous sub components are RoHS compliant.
