Hello
Please tell me about Assella data rates.
https://www.e-consystems.com/jp/Cypress-CX3-THine-ISP-13MP-RDK-jp.asp
Data rate when communicating at Ultra HD (3840×2160)15fps
about 1.9Gbps = 3840x2160x15fpsx16bit/1000000000
When the YUV422 of Cypress CX3 is selected (16bit width),the maximum data rate is exceed(1.6Gbps).
Question
When this happens, is CX3 doing 24-bit transfer?
I want to know the CX3 Mipi setting value and the setting values of CyU3PMipicsiSetIntfParams and CyU3PMipicsiGpifLoad in this case.
Solved! Go to Solution.

There is no settings for 32 bit stream format.
In terms of YUV, there are 3 types of YUV422 8bit mode format and YUV422 10 bit mode.
Please ask the customer to read CX3 stream format on the TRM. Especially, "1.6 CX3 MIPI CSI-2 Stream Formats"
After that, could you let me know the question from the customer if it still exists?
Best regards,

You can set 24-bit GPIF bus width to achieve high bandwidth. (CY_U3P_MIPICSI_BUS_24 is defined in CyU3PMipicsiBusWidth_t structure for setting of CyU3PMipicsiGpifLoad)
For more information, you can refer to the CX3 examples in FX3 SDK. C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware
After that, could you let me know which parameter you are not clear?
Best regards,

Thank you for your response.
I want to know the value of data Format which is an element of CyU3PMipicsiCfg_t structure for setting to
MIPI CSI-2 Receiver(YUV422 32bit) / Parallel Output(YUV422 24bit).
Currently,it is set to CY_U3P_CSI_DF_YUV422_8_2 for setting to MIPI CSI-2 Receiver(YUV422 16bit) / Parallel Output(YUV422 16bit).
