Figure 31 shows the quad alignment mode in the ORSO42G5.
Figure 31. Receive SONET Mode, Quad Alignment Mode – ORSO42G5
SONET Mode Receive Timing – ORSO82G5
This section contains timing diagrams for major interfaces of this block to the FPGA logic when SONET frames are
to be transferred.
When operating in SONET mode, the entire SONET frame is sent to the FPGA. In multi-channel alignment
mode(s), data from all channels within an alignment group are aligned to the A1A2 framing bytes.
Each SONET frame is 125μs. The frame starts with 36 clock cycles (77.76 MHz) of TOH followed by 1044 clock
cycles of SPE, followed by 36 clock cycles of TOH, 1044 cycles of SPE.
The DOUTxx_SPE signal indicates TOH or SPE in the data (low for TOH, high for SPE)
Twin pairs are AA, AB (group A1), AC, AD (group A2), BA, BB (group B1) and BC, BD (group B2)
Figure 32 shows the SONET twin alignment mode timing for the ORSO82G5. The frame pulse and SPE indicators
are show for each of the two channels (AA, AB) in twin alignment.
