Figure 12. Four Channel Alignment of SERDES Blocks A and B
ORT82G5 Multi-channel Alignment
The ORT82G5 has a total of eight channels (four per SERDES block). The incoming data of these channels can be
synchronized in several ways or they can be independent of one other. Two channels within a SERDES block can
be aligned together. Channel A and B and/or channel C and D can form a pair as shown in Figure 13. Alternately,
all four channels of a SERDES block can be aligned together to form a communication channel with a bandwidth of
10 Gbps as shown in Figure 14. Finally, the alignment can be extended across both SERDES block to align all
eight channels in ORT82G5 as shown in Figure 15. Individual channels within an alignment group can be disabled
(i.e., powered down) without disrupting other channels.
