Custom transceiver PCS/PMA interface width?

I currently have a Cyclone 10 GX and I was testing the XCVR_NativePhy IP and the XCVR_ATXPLL IP. I succeeded in setting up a Basic (Enhanced PCS) transceiver at 10400 Mbps with a 64 bit wide PCS/PMA ...

I am doing a custom interface. When I was testing the 10.4 Gbps with a 64 bit wide PCS/PMA interface, I was clocking the parallel data in at 162.5MHz which gave me the 10.4 Gbps constant stream (I want a constant stream of data). If I will now be running at 10 Gbps with only 20 bit wide PCS/PMA does the transceiver handle clocking the parallel data in at 500 MHz so I can get all 100 bits into the desired 10nS span for a constant stream of data?
