1.4.1.6. Frame Synchronizer

Note: The frame synchronizer is only used in Interlaken configurations.

The frame synchronizer block achieves lock by looking for four synchronization words in consecutive metaframes. After synchronization, the frame synchronizer monitors the scrambler word in the metaframe. After three consecutive mismatches, the frame synchronizer deasserts the lock signal and starts the synchronization process again. Lock status is available to the FPGA fabric.
