VSC7182

The VSC7182 is a full-speed quad Fibre Channel and Gigabit Ethernet transceiver IC. Each of the four ransmitters has a 10-bit wide bus, running up to 136MHz, which accepts 8B/10B encoded transmit characters nd serializes the data onto high-speed differential outputs at speeds up to 1.36Gb/s. The transmit data can be ynchronous to the reference clock, a common transmit byte clock or a per-channel transmit byte clock. Each eceiver samples serial receive data, recovers the clock and data, deserializes it into 10-bit receive characters, utputs a recovered clock and detects Comma" characters. The VSC7182 contains on-chip Phase-Lock Loop PLL) circuitry for synthesis of the baud-rate transmit clock and extraction of the clocks from the received serial treams. The VSC7182 also includes a receiver squelch circuit to control the parallel data bus in the absence of erial input.
