4. Backplane Ethernet 10GBASE-KR PHY IP Core
This transceiver PHY allows you to instantiate both the hard Standard PCS and the higher performance hard 10G PCS and hard PMA for a single Backplane Ethernet channel. It implements the functionality described in the IEEE Std 802.3ap-2007 Standard. Because each instance of the 10GBASE-KR PHY IP Core supports a single channel, you can create multi-channel designs by instantiating more than one instance of the core. The following figure shows the 10GBASE-KR transceiver PHY and additional blocks that are required to implement this core in your design.
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 Altera 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—Forward Error Correction (FEC) function is an optional feature defined in Clause 74 of IEEE 802.3ap-2007. It provides an error detection and correction mechanism allowing noisy channels to achieve the Ethernet-mandated Bit Error Rate (BER) of 10-12 .
