MAC - Fast Ethernet Media Access Controller

alt

The MAC Ethernet Controller implements Carrier Sense Multiple Access with Collision Detection (CSMA/CD) algorithms defined by IEEE 802.3 for media access control over the 10 and 100Mbps Ethernet.

The controller is available with most popular Ethernet PHY interfaces and an OCP socket as a system bus interface. The socket allows straightforward implementation of any other system bus interface, with AMBA® AHB and generic PVCI interface wrappers included in the delivery package.

The MAC controller is also available in a size-optimized Lite version. This version still implements full 802.3 CSMA/CD standard 10/100 Mbps Ethernet operation modes, but uses simplified FIFO interface and operates directly on input/output signals instead of instatiating a DMA controller and CSRs.
