DPA FIFO

In DPA-FIFO mode, the DPA FIFO synchronizes the re-timed data to the high-speed LVDS clock domain.

The DPA clock may shift phase during the initial lock period. To avoid data run-through condition caused by the FIFO write pointer creeping up to the read pointer, hold the FIFO in reset state until the DPA locks.
