Hi all

 

I want to know that the i.MX6D can be received 3MP at 60fps with MIPI-CSI2.

In connection with the above, I have question about how to calculate MIPI-CSI2 required operating frequency.

 

The maximum bandwidth in MIPI-CSI2 4lane is 3,200Mbps (= 800Mbps/lane x 4lane).

Addition for this, there are following examples in RM(Rev3.0).

 

To be calculated from the example, I think it is overflowed.

The calculation result is below.

 

6Mpixel x 24bit x 15fps x 1.5cycles/pixel = 3,24Mbps

 

Does my calculation is wrong ?

Please tell me how to calculate.

Also please tell me how to calculate the required operating frequency.

 

 

Add info:

I posted the following question before but no one answered.
