General Description

The VSC7145 is a dual-speed Fibre Channel, Gigabit Ethernet and InfiniBand Serializer/Deserializer (SerDes) optimized for performance and power in an industry-standard pinout. It accepts 10-bits of SSTL, 8B/10B encoded transmit data, latches it synchronously to the Transmit Byte Clock (TBC) and serializes it onto the SO differential output at a baud rate which is 10, 20 or 40 times the REFCLK frequency.
