5.14.2. Differential I/O Bit Position

Data synchronization is necessary for successful data transmission at high frequencies.

The following figure shows the data bit orientation for a channel operation and is based on the following conditions:

  • The serialization factor is equal to the clock multiplication factor.
  • The phase alignment uses edge alignment.
  • The operation is implemented in hard SERDES.

For other serialization factors, use the Intel® Quartus® Prime software tools to find the bit position within the word.
