Even at 8 bit the uncompressed payload of SD 4:2:2 is going to clear 100Mbps, before any timecode audio or metadata get factored in.
According to my refference:
SDI A (composite) is 143 Mbps, SDI C (4:2:2) is 270 Mbps, SDI D is 360 Mbps.

The capture card has to be recordaing at one of the SDI data rates. If it reduces it, then thats compression.
