The datasheet you posted lists all pixel drive mode at 24.17fps on the SLVS-EC interface for the IMX492. The 41MP sensor is/was the IMX594CQR, the original spec sheet is no longer publicly available but there are still sections of the spec sheet floating around.I have seen only screenshots of this rumoured 41MP datasheet which has never been in the public portfolio but it looked like the very same 47MP design. The only difference was that it was listed as 4/3 sensor Instead of oversized "1.4" and this 41MP is indeed the maximum 4:3 aspect ratio area that fits inside MFT image circle.
I'm not sure which IMX492 datasheet you are reading because the official one behind the link lists 30fps frame rate for full 8k (17:9) at "Basic Drive Mode". It doesn't even list 4k or 6k frame rates and I'm absolutely certain that there is no consumer sensor that can read [email protected] Even [email protected] is still a tall order for full sensor width readout.
