Using the "Basic (Enhanced PCS)" and "Basic with KR FEC" Configurations of
Enhanced PCS
You can use Arria 10 transceivers to configure the Enhanced PCS to support other 10G or 10G-like
protocols. The Basic (Enhanced PCS) transceiver configuration rule allows access to the Enhanced PCS
with full user control over the transceiver interfaces, parameters, and ports.
You can configure the transceivers for Basic functionality using the Native PHY IP Basic (Enhanced
PCS) transceiver configuration rule.
Basic with KR FEC is a KR FEC sublayer support with a low latency physical coding sublayer (PCS). The
KR FEC sublayer increases the bit error rate (BER) performance of a link. Use this configuration to
implement applications with low latency or low BER requirements or applications such as 10 Gbps or 40
Gbps Ethernet over backplane (10GBASE-KR protocol).
The Forward Error Correction (FEC) function is defined in Clause 74 of IEEE 802.3ap-2007. FEC
provides an error detection and correction mechanism that allows noisy channels to achieve the Ethernet-
mandated Bit Error Rate (BER) of 10
-12
. The FEC sublayer provides additional link margin by
compensating for variations in manufacturing and environmental conditions. To distinguish it from other
FEC mechanisms (for example, Optical Transport Network FEC), FEC as defined in Clause 74 of IEEE
802.3ap-2007 is called KR FEC.
Note:
This configuration supports the FIFO in phase compensation and register modes, and KR FEC
PCS blocks. You can implement all other required logic for your specific application, such as
standard or proprietary protocol multi-channel alignment, either in the FPGA fabric in soft IP or
use Altera's 10GBASE-KR PHY IP core product as full solutions in the FPGA.
