WebThe synchronizer is a 1-bit wide and 6-bit deep FIFO buffer that compensates for the phase difference between dpa_fast_clock from the DPA block and the fast_clock that the I/O PLLs produce. The synchronizer can compensate only for phase differences, not frequency differences, between the data and the input reference clock of the receiver. WebJul 6, 2024 · Fig 2.
