DPA Mode
In DPA mode, the DPA circuitry automatically chooses the optimal phase between the
source-synchronous reference clock and the input serial data to compensate for the
skew between the two signals. The reference clock must be a differential signal.
Figure 8–12
DPA_diffioclk clock to write serial data into the synchronizer. Use the
LVDS_diffioclk clock to read the serial data from the synchronizer. Use the same
LVDS_diffioclk clock in the data realignment and deserializer blocks.
IOE Supports SDR, DDR, or Non-Registered Datapath
