This is Adaptive Cable Equalizer. 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.
