W110 Dual-Speed Ethernet Controller

100Mbps + 10Mbps Ethernet Media Access Controller Mega Macrofunction

DESCRIPTION

The W110 is a 100BASE-T Ethernet Media Access Controller (MAC) mega macrofunction for dual-speed

operation (100Mbps/10Mbps) and an MII interface. Implemented in 0.5碌m and 0.8碌m technologies, the

W110 supports a wide range of physical layer (PHY) devices, including both 100Mbps and 10Mbps

devices for wired, optical, and wireless networks, operating in half- or full-duplex mode.

The W110 mega macrofunction is available in various configurations, depending upon customer parti-

tioning requirements. The W110 contains two main submodules, called MAC110 and PCS110. The

MAC110 submodule contains the key transmit/receive functions and performs the CSMA/CD function

specified in ISO/IEC 8802-3: 1993 and the supplemental IEEE standard 802.3u-1995. The PCS110 submod-

ule contains various PHY support modules and MII support.

Potential applications include network interface controllers (NICs), multiport switches, switching routers,

hubs, and test equipment.

The MAC110 submodule contains ~10.1k gates. The final top-level gate count is determined by which par-

ticular PCS option is chosen by the user. The W110M option (transmit and receive function with MII inter-

face only) contains ~7.1k gates. A gate-level model of the mega macrofunction is available in Verilog or

VHDL.
