Change clock frequency for Sony FCB-EV7520A

AKSadk — Wed, 03 Jul 2019 12:16:27 GMT

Hallo,

currently i am working with camera Sony FCB-EV7520A. The communication with the module is achieved via LVDS interface using VISCA protocol. As you can see in the attached photo, it is written that for the output format 1080p/30 the Pixel CLK should be 74.25 MHz. But the problem is: when i set the frame rate to 30 frame per second using the hex command (81 01 04 24 72 00 07 FF), the clock output remains at 148.5 MHz.

How shall i change the clock frequency of the module?

Looking to hear from you.

regards,
