10GBASE-KR PHY IP Core
The 10GBASE-KR Ethernet PHY IP core supports the following features of Ethernet standards:
• Auto negotiation for backplane Ethernet as defined in Clause 73 of the IEEE 802.3 2008 Standard. The
10GBASE-KR Ethernet PHY MegaCore Function can auto negotiate between 1000BASE-X,
1000BASE-KR , and 1000BASE-KR with FEC.
• 10GBASE-KR Ethernet protocol with link training as defined in Clause 72 of the IEEE 802.3 2008
Standard. In addition to the link-partner TX tuning as defined in Clause 72, this PHY also automati‐
cally configures the local device RX interface to achieve less than 10
-12
bit error rate (BER) target.
• Gigabit Media Independent Interface (GMII) to connect PHY with media access control (MAC) as
defined in Clause 35 of the IEEE 802.3 2008 Standard
• Forward Error Correction (FEC) as defined in Clause 74 of the IEEE 802.3 2008 Standard
The Backplane Ethernet 10GBASE-KR PHY IP core includes the following new modules to enable
operation over a backplane:
• Link Training (LT)— The LT mechanism allows the 10GBASE-KR PHY to automatically configure the
link-partner TX PMDs for the lowest Bit Error Rate (BER). LT is defined in Clause 72 of IEEE Std
802.3ap-2007.
• Auto negotiation (AN)—The 10GBASE-KR PHY IP core can auto-negotiate between 1000BASE-KX
(1GbE) and 10GBASE-KR (10GbE) PHY types. The AN function is mandatory for Backplane
Ethernet. It is defined in Clause 73 of the IEEE Std 802.3ap-2007.
• Forward Error Correction (FEC)—FEC function is an optional feature defined in Clause 74 of IEEE
802.3ap-2007. It provides an error detection and correction mechanism.
