1.6 Reference Design 2B: PMA with Bit-slip Feature

This reference design example implements the PolarFire transceiver in native PMA mode with Bit-slip feature. It includes a pattern generator to generate a 40-bit counter. The pattern checker checks the received data and compares it with the expected counter. The PolarFire transceiver is configured in native PMA mode.

The deserializer has a Bit-slip feature for word alignment. In this mode, the CDR slips to the next bit from the deserializer. This feature helps with building word alignment logic in the fabric. It is available for PMA only applications using fabric-based alignment. The configurator enables this using RX_SLIP input port.

For more information about Bit-slip feature, see the PolarFire Family Transceiver User Guide .

The following figure shows the block diagram for the PMA design with Bit-slip feature.
