Hi
We are using a Onsemi parallel camera (BW raw image) on RT1170 MCU, and have some questions concerning the CSI clocks.
According to the reference manual the CSI module has a maximal clock of 66MHz.It also states that csi_hclk must be 10% faster than the pixel clock.I assumed that csi_hclk in MCUExpresso was CSI_CLK_ROOT, which has a maximum speed of 66MHz.
We have set this clock to 66MHz, and the connected camera to a pixel clock of 59.4MHz, and it works fine.
But the maximum frame rate of this system is rather low (320x240 94FPS), so we would like to ask some questions:

Hi @JohnnyK ,
1. No, csi_hclk is from BUS_ROOT_CLOCK, which is 240M. Please refer to table 15-2 at page 1453.
2. The maximum pixel clock is 80M which comes from camera. Please see table 69 in datasheet.
3. No, they needn't.
4. No
5. Yes, MIPI CSI finally connect to CSI.

Jing
