Figure 23. Receive Clocking Diagram for SONET Mode Quad-Channel Alignment in Block A – ORSO42G5
Multi-channel Alignment in SONET Mode (ORSO82G5)
The alignment FIFO allows the transfer of all data to a common clock. The FIFO sync block allows the system to be
congured to allow the frame alignment of multiple slightly varying data streams. This optional alignment ensures
that matching SERDES streams will arrive at the FPGA end in perfect data sync. It is important to note that for all
aligned channels in a group, the SERDES transmitters on the other side of the high-speed link must all be transmit-
ting data at exactly the same frequency (0 ppm difference), i.e., using a common clock source.
The ORSO82G5 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 can be
aligned together; channel A and B and/or channel C and D can form a pair as shown in Figure 24. Alternately, all
four channels in a SERDES block can be aligned together to form a communication channel with a bandwidth of 10
Gbps as shown in Figure 25.
Finally, the alignment can be extended across the SERDES blocks to align all eight channels in the ORSO82G5 as
shown in Figure 26. Individual channels within an alignment group can be disabled (i.e., powered-down) without
disrupting other channels. Note that the SERDES channel that is powered down can not be the source of the RSY-
SCLKxx that is clocking the read side of the alignment FIFO. When a disabled channel becomes active as part of
an alignment group, the group may need to be re-aligned. Then the whole group needs to be resynched. This
would only need to occur if the transmitting frame pulse for the new link is different from the rest of the group.
