hi team,

may i know how to calculate the MIPI serial rate based on 940? what's the difference with 954 mipi serial rate? if i want to config pattern generator 1280*720 30fps, 400MHz, how to config? thanks.

940 datasheet section 8.4.1 shows MIPI data rate calculation.
940 MIPI output rate depends on PCLK, while 954 MIPI output have a few fixed rate.

I will get back to you on patgen configuration.

Thanks Charley, additional question about 954 ALP GUI, is the "Linked to " frequency is FPD3_PCLK or input PCLK? i found in RAW12 mode, input PCLK is 75M, but here i got 50M, but not sure whether i am correct. thanks.

Hi Phil,
Sorry for the late reply. In ALP, it shows the FPD3 clock.

You are getting the correct reading.
