How to configure the rate of DS953 I2C output?

It works, thanks very much!

One more question.

As connection like sensor->ds953->ds954->soc, when ds953 is configured as CSI-2 Synchronous mode, the reffrence clock should be the clock of ds954?

Then what is the clk sent on FPD-LINK?

Thanks for replying.

However, I'm a little confused, as the default values of ds953 for reg 0x05/0x06/0x07 are 0x03/0x41/0x28, why can I get an output clk of 25MHz for the sensor?

I think, it should be caculated as 50/1/4/40=0.3125MHz. Or if I want to generate a clock of 25MHz for the sensor, the DS954 should output the singnal with 4GHz.

Hello Xn,

I'm confused on the question. Are you asking about how to configure the CLKOUT for 953 to the sensor? By default for 954/953 in synchronous mode, the 953 will output 25MHz CLKOUT. Are you trying to program a different CLKOUT frequency? If so, what frequency do you need?

Hi, I just want to know the source of 25MHz.

Actually, by default, my board can output a clock of 25MHz tosensor. However, I don’t know why. As the div and m/n are 4 and 1 /40. Then 954 should provide a clock of 4GHz to 953, right? Then how can 954 output 4GHz clock to 953?

Thanks!
