Description
Yes, Arria® V GX devices support the Rate Match FIFO option when the word aligner is in manual alignment mode, and the PMA-PCS interface is 20 bits wide.
Due to a mistake in Figure 5-6 of the Transceiver Custom Configurations in Arria V Devices handbook (PDF) the Rate Match FIFO is shown as disabled.
Resolution
This problem will be fixed in a future version of the Transceiver Custom Configurations in Arria V Devices handbook (PDF).
