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 f...
