General Description
The VSC7133 is a full-speed Fibre Channel and Gigabit Ethernet Transceiver with industry-standard pinouts. It accepts 10-bit 8B/10B encoded transmit data, latches it on the rising edge of the TTL/PECL REFCLK and serializes it onto the TX PECL differential outputs at a baud rate which is ten times the REFCLK frequency. Serial data input on the RX PECL differential inputs is resampled by the Clock Recovery Unit, deserialized onto the 10-bit receive data bus synchronously to complementary divide-by-twenty clocks.
