DS90UB935-Q1: Configuration of serializer 935, deserializer UB954 and sensor chip OX01F10

Part Number: DS90UB935-Q1
Other Parts Discussed in Thread: DS90UB954-Q1,

Hi team,

Here's an issue from the customer may need your help:

The module consists of UB935 with sensor chip OX01F10 where 935 and 01F10 use a 2-lane MIPI signal with the data type raw and 935 and 954 are YUV422.

Is there anything to consider for the 935 configuration? The 935 works at synchronous mode, and the current profile is able to recognize the I2C address of the chip, but it does not make a diagram.

The following are the configuration parameters:

//TI935
0xfff8,0x30,
0xffff,0x64,

0x01,0x03,
0x02,0x53, //2lane Continous CLK

//I2C MODE
//0x0b,0x13,
//0x0c,0x26,
0x0b,0x7F,
0x0c,0x81,


//GPIO3 pulleUp Pwdn; GPIO0 as for Fysnc
0x0e,0x81,//GPIO_0/1 output enable 30
0x0d,0x18,//GPIO_0/1 01 03
//0x0d,0x0c,


//0x0e,0xc3,
//0x39,0x6c,
//0x41,0x6c,
0x39,0x00,
0x41,0x00,

0x33,0x23,
0x4c,0x01,
0x20,0x08,
//0x58,0x7a,
0x58,0x7e,
0x7c,0x81,


//24M MCLK output

0x07,0x7d //7d
0x06,0x63 //63


0xfff8,0x60
0xffff,0x0a
//0x58,0x5e

Could you help check this case? Thanks.

Best Regards,

Cherry

    Cherry,

    I don't understand what you mean by this statement:

    Cherry Zhou said:

    The DS90UB935-Q1 and DS90UB954-Q1 pass through CSI-2 data packets as received. They do not adjust data type of the video. So if the sensor is providing RAW video to the 935, then the 954 will also output RAW packets. 

    Also I'm not sure what the problem is that you are having from this explanation. What does this mean?

    Hi Casey,

    Thanks for your support.

    The 935 is configured for YUV422 output, but the sensor provides raw video to 935.

    Regarding to I2C, the slave ID of 935 and the slave ID of sensor can be read through 954, but there is no image. 

    Thanks and regards,

    Cherry,

    There is no function in the 935 to have the serializer convert input RAW video to YUV422 or any other format. So I'm still confused on what you are trying to do here. 

    Best Regards,
