Note: The 64B/66B encoder is used only in 10GBASE-R configurations.

The 64B/66B decoder block contains a 64B/66B decoder sub-block and a receiver state machine sub-block. The 64B/66B decoder sub-block converts the received data from the descrambler into 64-bit data and 8-bit control characters. The receiver state machine sub-block monitors the status signal from the BER monitor. If the status signal is asserted, the receiver state machine sends local fault ordered sets to the FPGA interface.

The 64B/66B decoder block is designed in accordance with the 10GBASE-R protocol specification as described in IEEE 802.3-2008 clause-49.
