Are you planning to cascade SD3 and FX3? If so, it is not possible as SD3 has no GPIF Lines. The only option is FX3S with 16 Bit GPIF Lines.
Also, are you planning to store the incoming video data in the SD card? If so, please note that this is not possible as the SD interface cannot stream incoming video data fast enough.

I was planning to use SD3 after FX3 to store converted USB data. Unfortunately, SD3 has low speed specs and I am now looking for alternatives.
Thanks for the help,
I am planning to use FX3S for recording video data to an SD card. However, I am slightly confused when you say "SD interface cannot stream incoming video data fast enough". According to the FX3S datasheet supports SD 3.0 (SDXC) UHS-1; in four-bit transfer mode could transfer up to 50 MB/s. Could you please advice.
Data rates that my device needs to handle is much higher than 50MB/sec without compression. As a result, I commented as you have pointed out.
