Hi Arai,
Q1-1) If the value of "Output Pixel Clock [Mhz]" exceeds the Max value, what parameter should I correct?
Q1-2) Please tell me the reason mentioned above. |
Generally, the following will decrease the Output pixel clock:
a. Increasing pre-divider value and/or
b. Increasing parallel clock divider and/or
c. choosing lower PLL Out range
d. Decreasing the Multiplier of unit clock.
But in your case, the output format (which is in the right column of the configuration tool, that is, CX3 MIPI Interface Configuration) is chosen to be RAW8. With this output format, the incoming data cannot be sent to GPIF while meeting the required frame rate. So, please change the output format to RGB888 (You need not change Data format in the left column of the tool, that is, MIPI CSI2 Inputs)
After changing the output format, min required pixel clock will change to a value less than 100MHz as expected. Then you can use any of the above options to bring the output pixel clock between min and max.
Q2) Please find attached, the value of "Output Pixel Clock [Mhz]" range is [Min:204.12| and [Max:100]. Why is MIN larger than MAX? |
As mentioned above, with RAW8 output format and with the shared settings of the image sensor(that is resolution, blanking values etc), the incoming data cannot be sent over GPIF. Because of this, tool is showing min value greater than max.
