Description
The GV8500 is a high-speed BiCMOS integrated circuit
designed to drive one or two 75Ω coaxial cables.
The GV8500 can drive data rates up to 2.970Gb/s, and
provides two selectable slew rates in order to achieve
compliance to HDcctv 1.0, ST 292 at 1.485Gb/s, ST 424 at
2.970Gb/s, and ST 259 at 270Mb/s.
The GV8500 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 GV8500 is Pb-free, and the
encapsulation compound does not contain halogenated
flame retardant.
This component and all homogeneous subcomponents are
RoHS compliant.
