GS9077 Data Sheet
Description
The GS9077 is a high-speed BiCMOS integrated circuit
designed to drive one or two 75Ω 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.
