Hello

   

 

   

I checking the CX3 for our new product.

   

I have a some questions about CX3 , Please kindly answer.

   

 

   

I found that “two 10bit or 12bit pixels can be packed an output per PCLK using the 24 bit output format” in the your document.

   

If I use this function , How much can receive the image of 13MP?

   

Can receive the over 12 fps?

   

 

   

And I want control the “MIPI CSI-2 Block” to use 24 bit band width when receive the RAW10.

   

Can I receive the 24bit data of RAW10 per PCLK as “RAW10_PCLK.jpg”?

Hi,

   

Yes. This data rate can be supported.

Hi

   

Thank you for your answer.

   

Please answer about the second question.

   

Can I receive the 24bit data of RAW10 per PCLK as “RAW10_PCLK.jpg”?

Sir,

   

I think any input data, raw10,raw12 or raw14 ,can be treated as raw8, for example, our image sensor, 1080P60,raw 10 bayer.

   

1920 *10 = 19200 bit per line, which is 2400 byte,so,if 24bit output is selected, 19200/24 = 800 cycles

   

the new resolution is 19200/8 = 2400.

   

So,CX3 is just a transparent transmitter or carrier, the software on PC will receive 2400 bytes/line, and then unpack them to raw10 image.

   

Is it right?

If there is no padding of data, then PC will receive 2400 bytes/line. Zeros may be padded when there is mismatch between GPIF II bus width and the dataFormat parameter in the MIPICSI configuration structure (CyU3PMipicsiCfg_t)
