The Multi-Rate Ethernet PHY FPGA IP core can dynamically support multiple data rates without any design regeneration or device reconfiguration. This IP allows the creation of a 1G to 10G configuration that allows dynamic reconfiguration across all Ethernet rates from 10M, 100M, 1G, 2.5G, 5G, and 10G.The 2.5G and 5G Ethernet configurations were introduced to support higher bandwidth on widely deployed CAT5e and CAT6 cabling in enterprise and metro area networks.
Multi-Rate Ethernet PHY FPGA IP
Overview
Key Features
- Implements the Ethernet protocol as defined in clause 36 of the IEEE 802.3 2005 standard.
- Consists of a physical coding sublayer (PCS) function and an embedded physical medium attachment (PMA).
- Dynamically switchable PHY operating speed.
- 1G/2.5G, 2.5G, 10M/100M/1G/2.5G, 1G/2.5G/10G (MGBASE-T), 10M/100M/1G/2.5G/5G/10G (USXGMII), 10M, 100M, 1G, 2.5G, 10G (MGBASE-T) operating modes.
- Users needing Copper-PHY capability for USXGMII, MGBASE-T modes will need to use an external PHY chip.
