IC revision7

Description

The GV7700 is a serial digital video transmitter for High Definition component video. With integrated cable driving technology, the GV7700 is capable of transmitting compressedvideo at 270Mb/s or 540Mb/s, or uncompressed video at 1.485Gb/s or 2.97Gb/s, over 75Ω coaxial cable, ordifferentially over 100Ω twisted pair cable.The GV7700 integrates the High Definition Visually Lossless CODEC (HD-VLC™) technology, which has been developedspecifically to reduce the transmission data rate of HD video over both coaxial and unshielded twisted pair (UTP) cable. This is achieved by encoding the HD video, normallytransmitted at a serial data rate of 1.485Gb/s, to the same rate as Standard Definition (SD) video, at 270Mb/s serial data rate.
