function, 16:1 mux/demux and high speed I/O. The VSC8476
also offers an additional data output with programmable preemphasis 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.
