Abstract
A system and method are provided for deinterleaving differential inverse multiplexed (DIM) virtual channels in a 40G Ethernet receiver. The method accepts a 10.3125 gigabits per second (Gbps) (10G) Ethernet virtual channel with 64B/86B blocks, including periodic Lane Alignment Marker (LAM) blocks. The 10G virtual channel is deinterleaved into two 5.15625 Gbps (5G) virtual channels by: 1) deinterleaving consecutive blocks from the 10G virtual channel into the 5G virtual channels in an alternating order, and 2) reversing the order of deinterleaving in response to each detected LAM block. Then, the method supplies the 5G virtual channels (i.e. to a MAC module).
