The VSC8476 is a 10Gb Ethernet and 10Gb

Fibre Channel Serial Transceiver that has a

10-Gigabit

Attachment

Unit

Interface

(XAUI) I/O, 8B/10B Encoder/Decoders,

64B/66B

encoder/decoder,

gearboxing

function, 16:1 mux/demux and high speed I/O. The VSC8476

also offers an additional data output with programmable pre-

emphasis to enable longer links for copper. With these

functions the VSC8476 implements the IEEE 802.3ae and T11

10GFC XGMII Extender Sub-layer (XGXS), Physical Coding Sub

layer (PCS), and Physical Medium Attachment (PMA). The

VSC8476 supports both the 10.3Gb/s and the 10.5 Gbps as

defined by IEE802.3ae and T11 10GFC respectively. The device

operates using both 1.2V and 1.8V supplies for optimal power,

dissipating a typical power of only 1 Watt. The VSC8476 is

available in a 17mm x 17mm 256 ball package with 1mm ball pitch.
