Description

The GS9077 is a high-speed BiCMOS integrated circuit

designed to drive one or two 75

Ω co-axial cables.

The GS9077 may drive data rates up to 540Mb/s and

provides a disable pin that may be used to power down

the output stage.

The GS9077 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 GS9077 is Pb-free, and the

encapsulation compound does not contain halogenated

flame retardant.

This component and all homogeneous subcomponents

are RoHS compliant.
