Figure 1–69. Transceiver Configuration in SDI Mode
Altera recommends driving rx_bitslip port low in configuration where
low-latency PCS is not enabled. In SDI systems, the word alignment and framing
occurs after de-scrambling, which is implemented in the user logic. The word
alignment therefore is not useful, and keeping rx_bitslip port low avoids the word
aligner from inserting bits in the received data stream.
