DS90UB960-Q1: Questions about compatibility of 960

Part Number: DS90UB960-Q1

Hi team,

1.SoC side 960 is connected with 3M camera Serializer 953, the mode of 960 is configured as CSI-2. Am I right? If I would like to use 933 which is YUV video format to connect with 960. should I use RAW mode as below pic? and how do I judge which RAW mode I can use because there has RAW12 Low Frequency Mode, RAW12 High Frequency Mode and RAW10 Mode three different modes here. Follow the previous question if I use a 1Mp camera and a 3Mp camera with 933 and 953 then connect to 960. how do I judge which FPD3_MODE I can use? 

2. GPIO of 960 can be used for SYNC input and LOCK output. The LOCK output can be configured according to the register as . My question is that Can 953 GPIO input signal send to 960 GPIO output? and Can it use multiple channels for this behavior?

BR,

Jimmy

    Hi Jimmy,

    Using the 953 and 960 together, you will be able to use CSI-2 mode as the FPD3 mode. The modes can be configured based on system preference and serializer compatibility. For example, using the DS90UB933, RAW data mode must be used. The data format for YUV422 10 bit has the same pixel format of RAW10. RAW8 and RAW12 adhere to the same YUV422 8 bit and 12 bit. RAW modes will have difference in back channel speeds and forward channel frame structure. 

    Regarding the second question, GPIO signals input to the 953 can be configured as a forward channel GPIO to output on the 960. Forward channel GPIOs are configured based on the connected RX port. Forward channel GPIOs are discussed in Section 7.4.11.3 of the DS90UB960 datasheet. 

    Let me know if there are any remaining questions!

    Best,
