DS90UB954-Q1: Output data array in RAW10 mode

Tomoaki Yoshida91

Part Number: DS90UB954-Q1

Hi team,

Our customer will use 954 as RAW10 mode connected 913A.

Please tell me the correlation between the YUV input data of 913A and the data array of the output in RAW10 mode of 954.

Best regards,

Hi,
The 954 will output CSI-2 data. 954 register 0x70[5:0] should be used to change the RAW10 data type to YUV data type according to CSI specification.

Sincerely,
Charley Cai

Hi Charley-san,

Thank you for your reply.

I do not know what value should be set for 0x70[5:0].

Is data array specified by the data protocol of MIPI CSI-2?

I have not been able to see the CSI-2 specification document.

Best regards,

Hi,
Yes, the data array is specified by MIPI CSI-2 protocol. Please refer to MIPI CSI-2 spec for the YUV data type value and data array.

Sincerely,

Hi Charley-san,

Thank you for your support.
We will check MIPI CSI-2 spec soon.
In RAW10 mode, what format is assumed for the input of 913A?
We are assuming YUV422.

Since YUV has several data formats, please let me know if there are restrictions on the input format.

Best regards,
Tomoaki Yoshida

Hi Tomoaki-san,
In RAW10 mode, 913A is configured to take 10 bit input. Any YUV format in 10 bits format is ok.

Sincerely,
Charley Cai

Hi Charley-san,

Thank you for your support.

I understand about input format.

We will evaluate 954 connected to 913A in RAW10 mode.

I'd like to confirm that the connection is correct at first.

Can I use the BIST mode from 954 to 913A at this time?

Best regards,

Tomoaki Yoshida

Yes, you could use BIST mode at this stage to check connection.

You could enable BIST by setting register 0xb3 on 954.
Please refer to 954 datasheet section 7.5.12 for BIST description and settings.

Sincerely,
Charley Cai

Hi Charley-san,

Thank you for your support.

And I'm sorry many times.

Finally please check whether the following recognition is correct.

I recognize that the RAW10 data output format of CSI-2 is as shown in the above figure.

At this time, the parallel input of 913A DIN [9] of the first PCLK corresponds to a9 of the first byte of CSI output in the above figure.

Then, DIN[0] of the first PCLK corresponds to a0 of the fifth byte.

Thereafter, DIN[9:0] of the second PCLK clock corresponds to b9 to b0 of the CSI output.

Is it correct recognition?

Best regards,

Tomoaki Yoshida
