12.3.2.2. Architecture

The 1G/2.5G/5G/10G Multirate Ethernet PHY IP for Agilex™ 3 devices implements the Ethernet protocol as defined in the IEEE 802.3 2005 Standard.

It consists of a physical coding sublayer (PCS) function and an embedded physical media attachment (PMA). You can dynamically switch the PHY operating speed. The IP leverages the Agilex™ 3 Ethernet hard IP transceiver for serial transmission with soft logic added to implement interface to MAC.

The following figure shows the HPS EMAC interface with the soft 1G/2.5G/5G/10G Multirate Ethernet PHY IP core.
