The PolarFire high-speed transceiver (PF_XCVR_ERM) is a hard IP block and
supports data rates from 500 Mbps to 12.7 Gbps. In this demo, PF_XCVR_ERM is
configured for the data rate of 10312.5 Mbps. It is configured with a CDR
reference clock of 156.25 MHz with lock to data selected as the CDR lock
mode. The PCS of the transceiver is interfaced with CORE10GMAC. It is
configured for the 64/66b mode with scrambler/descrambler enabled. The
scrambler, which is self-synchronizing, generates sufficient transitions to
aid data and clock recovery at the CDR. The following figure shows the
transceiver interface configuration.Figure 1-13. PF_XCVR
