General Description

The VSC7186 is a Quad Gigabit Ethernet Transceiver IC. Each of the four transmitters has a 10-bit wide bus, running at 125 MHz, which accepts 8b/10b encoded transmit characters and serializes the data onto high speed differential outputs at rates between 1.05 and 1.36 Gb/s. The transmit data must be synchronous to the reference clock. Each receiver samples serial receive data, recovers the clock and data, deserializes it into 10-bit receive characters, outputs a recovered clock and detects “Comma” characters. The VSC7186 contains on-chip PLL circuitry for synthesis of the baud-rate transmit clock and extraction of the clocks from the received serial streams.
