V-by-One PHY GF22FDX is designed for chips that perform high bandwidth data communication while operating at low power consumption. It is a multi-gigabit receiver macro that complies with video system, which is a flexible and robust solution that enable speed up to 4.0Gbps data receiver with optimized power and die size, also it can be easily fabricated and implemented in a video system. Each macro consists of multi-receiver channels, and one PLL and bias gen unit. The receiver performs dedicated equalizer, clock and data recovery (CDR),
S2P and self-test. Each of the channels can be turned off individually.
