Let me discuss about your case.
Seems that cx3 GPIF II spec not allowed to use over 48 fps in your image sensor.
Cypress restrict the pclk under the 100MHz, therefore when you want to send
1440 x 1440 x 90 (fps) frame in 1sec, it is totally need about 186MHz pclk.
I believe 48fps is the maximum I could transfer if the GPIF bus were set to 8 bits. I am hoping I can triple-up the data gathering and use 24bits on the GPIF, and thus be able to achieve the desired 90 FPS? This is the bit I am unsure about and need an expert to understand if the CX3 can do this.
never mind. figured it out.
