I'm looking to attach two CMOS camera modules to BF609 SOM . CAM1 will be mapped to PPI2 and CAM2 to PPI3. Both camera modules require external clock.
According to OV96xx datasheet:
Min Typcl Max
Input Clock Frequency 10 24 48 MHz
Input Clock Period 21 42 100 ns
Clock Duty Cycle 45 50 55 %
I'm considering on using clock generator such as SI5351A (http://www.silabs.com/support%20documents/technicaldocs/Si5351.pdf) with three free-running clock outputs - one for each module and one spare.
Does anyone have any experience doing something similar? Do I need to be concerned with clock synchronization between BF609's CLKOUT and SI5351 when dealing with two CMOS cameras? SI5351C product variant allows for external clock input and synchronization.
Would you have any alternative solutions and/or suggestions? Can I simply use scaled down to 24MHz output of CLKOUT to drive both CMOS modules?
Any feedback will be greatly appreciated.
