Hi @ShaneCCC,
By the way, I have certain confusion about the 1.5 Gbps (per lane ?!?!?) limitation as from this comment High FPS - #3 by JerryChang, it is said that the max CSI bandwidth is 2.5 Gbps per lane. And our bridge sensor uses 4 lanes → 10 Gbps theoretically, so there would no problem with output rate of 2.97 Gbps.
Also, the note you shared seems only relevant to SerDes Pixel Clock:
