VSC8476
XAUI to XFI 10GE & 10GFC Transceiver
GENERAL DESCRIPTION:
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.
