VSC8476 Datasheet 10 Gb E/FC Serial Transceiver with XAUI and XGMII I/O Features - 10 Gb E and 10 G Fibre Channel serial LAN transceiver - Fullypliantwith IEEE802.3ae(10 Gb E)and (10 G Fibre Channel) T11 Project-1413-D - XFI pliant - CML 10.3 Gbps to 10.5 Gbps high-speed front-end - 4 × 3.125 Gbps to 3.1875 Gbps XAUI I/O - XAUI lane programmability: lane swap, bit-order swap, invert, deskew, amplitude, emphasis, and equalization - 8b/10b encoders/decoders - XGMII I/O (1.5 V supply HSTL) - Integrated gearbox function - Support for data and control character 64B and 66B encoding and decoding - Clock rate disparity pensation - Multiple loopback modes - Multiple test pattern generation and checking - MDIO and two-wire serial interface management interfaces - JTAG access port - 1.2 V supply for low power consumption - 1.5 V supply for XGMII operation - Optional 1.5 V, 1.8 V, 2.5 V, or 3.3 V supply for TTL patibility - 1.2 W (typical) power in XAUI to XFI mode GENERAL DESCRIPTION The VSC8476 is a 10-gigabit Ethernet and 10-gigabit Fibre Channel serial transceiver, which provides a 10-gigabit attachment unit interface (XAUI) I/O, 8b/10b encoders/decoders, 10-gigabit media-independent interface (XGMII) I/O, 64b/66b encoding/decoding, gearbox function, 16:1 mux/demux, and high-speed I/O. With these functions, the VSC8476 implements the IEEE 802.3ae and T11 10 GFC XGMII extender sublayer (XGXS or PHY XS), physical coding sublayer (PCS), and physical medium attachment (PMA). The VSC8476 supports the 10.3 Gbps and the 10.5 Gbps rates as defined by IEEE 802.3ae and T11 10 GFC. All specifications refer to the higher 10.5 Gbps rate for consistency; the lower 10 Gb E rate is identified with parenthesis (10.3 Gbps). The device can operate using 1.2 V supply for optimal power and 1.5 V supply for the XGMII interface, dissipating a typical power of only 1.2 W. The VSC8476 is available in a 17 mm ×...
