67 W Max Power Dissipation • 208-Pin, 23mm BGA Packaging General Description The VSC7139 is a full-speed Quad Fibre Channel and Gigabit Ethernet Transceiver IC.
Each of the four transmitters has a 10-bit wide bus, running up to 136MHz, which accepts 8B/10B encoded transmit characters and serializes the data onto high speed differential outputs at speeds up to 1.
36Gb/s.
The transmit data can be synchronous to the reference clock, a common transmit byte clock or a per-channel transmit byte 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 VSC7139 contains on-chip (PLL) circuitry for synthesis of the baud-rate transmit clock and extraction of the clocks from the received serial streams.
