Preliminary

Single-Port 10/100 Mbit/s Ethernet Switch

• Filtering and switching at wire rates (up

• Flow control supported for both full-

duplex and half-duplex operation;

supports IEEE 802.3x PAUSE frame

flow control in full-duplex mode, and

supports user-enabled backpressure

flow control in half-duplex mode.

• Maintains and collects per-port and

per-host statistics at wire rates.

• Interfaces directly to industry-standard

100 Mbit/s transceivers with no glue

logic via the built-in Medium

Independent Interface (MII) port with

full support for the autonegotiation

function implemented by the PHY

devices.
