Figure 8–15. Data Realignment Timing
The data realignment circuit can have up to 11 bit-times of insertion before a rollover
occurs. The programmable bit rollover point can be from 1 to 11 bit-times,
independent of the deserialization factor. The programmable bit rollover point must
be set equal to or greater than the deserialization factor, allowing enough depth in the
word alignment circuit to slip through a full word. You can set the value of the bit
rollover point using the MegaWizard Plug-In Manager software. An optional status
port, RX_CDA_MAX, is available to the FPGA fabric from each channel to indicate when
the preset rollover point is reached.
