Intel® IXF1104 4-Port Gigabit Ethernet Media Access Controller

5.0Functional Descriptions

5.1Media Access Controller (MAC)

The IXF1104 MAC main functional block consists of four independent 10/100/1000 Mbps Ethernet MACs, which support interfaces for fiber and copper connectivity.

•Copper Mode:

—RGMII for 10/100/1000 Mbps full-duplex operation and 10/100 Mbps half-duplex operation

—GMII for 1000 Mbps full-duplex operation

•Fiber Mode:

—Integrated SerDes/OMI interface for direct connection to optical modules

—1000 Mbps full-duplex operation in fiber mode

The following features support copper and fiber modes:

•Programmable Options:

—Automatic padding of transmitted packets that are less than the minimum frame size

—Broadcast, multicast, and unicast address filtering on frames received

—Filter and drop packets with errors

—Pre-padded RX frames with two bytes (aligns the Ethernet payload on SPI3 and in network processor memories)

—Remove CRC from RX frames

—Append CRC to transmitted frames

•Performance Monitoring and Diagnostics:

—Loopback modes

—Detection of runt and overly large packets

—Cyclic Redundancy Check (CRC) calculation and error detection

—RMON statistics for dropped packets, packets with errors, etc.

•Compliant with IEEE Spec 802.3x standard for flow control

—Receive and execute PAUSE Command Frames

•Support for non-standard packet sizes up to 10 KB including loss-less flow control

Note: The IXF1104 MAC does not support 10/100 Mbps operation when configured in GMII mode.

The IXF1104 MAC is fully integrated, designed for use with Ethernet 802.3 frame types, and compliant to all of the IEEE 802.3 MAC requirements.

The IXF1104 MAC adds preamble and Start-of-Frame Delimiter (SFD) to all frames sent to it (transmit path) and removes preamble and SFD on all frames received by it (receive path). A CRC check is also applied to all transmit and receive packets. CRC is optionally appended to transmit
