General Description
The VSC7123 is a full-speed Fibre Channel and Gigabit Ethernet transceiver with industry-standard pinouts. The VSC7123 accepts 10-bit 8B/10B encoded transmit data, latches it on the rising edge of REFCLK and serializes the data onto the TX PECL differential outputs at a baud rate, which is 10 times the REFCLK frequency. Serial data input on the RX PECL differential inputs is resampled by the Clock Recovery Unit (CRU) and deserialized onto the 10-bit receive data bus synchronously to plementary divide-by-twenty clocks.
