IXF1110 10-Port 1000 Mbps Ethernet Media Access Controller
Functional Descriptions
Media Access Controller
General Description
The IXF1110 MAC main functional block consists of a 1000 Mbps Ethernet Media Access
Controller (MAC), supporting the following features:
The MAC is fully integrated, designed for use with Ethernet 802.3 Frame types, and is compliant
with all of the required IEEE 802.3 MAC requirements.
The 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. Packets with a bad CRC are marked, counted in the
statistics block, and may be optionally dropped or sent to the SPI4-2 interface.
MAC Functions
Section 5.1.2.1, “Padding of Undersized Frames on Transmit” on page 44
“Filtering of Receive Packets” on page 45
Padding of Undersized Frames on Transmit
The padding feature allows Ethernet frames smaller than 64 bytes to be transferred across the
SPI4-2 interface and automatically padded up to 64 bytes by the MAC. This feature is enabled by
setting bit 7 of the
