DS90UB936-Q1: YUV422 RAW10 mode

Shuji Ishiwata

Part Number: DS90UB936-Q1

Hi Team,

I have a question at DS90UB936-Q1.
I am thinking of transmitting YUV422 in RAW10 mode.
The serializer uses DS90UB913-Q1. The serializer PCLK is 25 MHz.
The 936 RAW10 mode is described as ranging from 50 MHz to 100 MHz.
Can I use RAW10 mode?
Do I need to use RAW12 mode?
RAW12 mode is recognition not defined in CSI-2.

Best Regards,
Ishiwata

Ishiwata,

Yes, you are right that the 25MHz PCLK is limited in the application between 933 and 936. there are two points:

1. Please check d/s 933 page6, the PCLK freq. range is limited to >50MHz. For external clock mode, the PCLK can be >=25MHz;

2. Only RAW10 mode can be used for your YUV422 video format, RAW12 can't be used here.

best regards,

Steven

Hi Steven,

Thank you your response.

The customer uses it with the following configuration.

YUV422(PCLK=25MHz) → DS90UB913-Q1 → DS90UB936-Q1 → MIPI-CSI2

Is transmission possible in 12-bit Low Frequency (LF) mode?

Best Regards,
Ishiwata

Hi Ishiwata,

For 12bits mode, the CSI package would be raw12 mode. but your case is YUV422, so the 12bits mode can't be used here.

For 10bits mode, as mentioned in d/s, if you use the external PCLK mode, it can work.

best regards,

Steven
