Description
The GV8601 is a high-speed BiCMOS integrated circuit
designed to equalize and restore signals received over 75Ω
coaxial cable.
The GV8601 is designed to support HDcctv 1.0, ST 292 and
ST 424, and is optimized for performance at 1.485Gb/s and
2.97Gb/s serial data.
The GV8601 features DC restoration to compensate for the
DC content of HDcctv 1.1 pathological test patterns.
The differential outputs can be DC-coupled to
industry-standard 3.3V and 2.5V CML logic using the
CMSET pin.
Power consumption is typically 195mW using a 3.3V
power supply. The GV8601 is lead-free, and the
encapsulation compound does not contain halogenated
flame retardant.
This component and all homogenous subcomponents are
RoHs compliant.
