DS90UB962-Q1: Initialization or Configurations sequence

Part Number: DS90UB962-Q1


Hi,

I am using DS90UB962-Q1 deserializer in my design.

I need to know the following details regarding the deserializer for software implementation :

1. What is the initialization sequence of DS90UB962-Q1?

2. Functional flow chart of DS90UB962-Q1.

    initialization will depend on your use case. Typically the device is strapped into the desired mode of operation and minimal initialization is needed.

    Could you share the use case?

    Hi Charley Cai,

    Thanks for your reply.

    I was not able to reply immediately since I got stuck in another urgent activities.

    Here are the use cases of my design:

    • DS90UB962 receives input from 4 imager with the pixel rate of 1280 x 800 at 30 frames per second.
    • De-serialized data is interfaced with processor in 12 bit Raw CSI format.
    • Usage of GPIO is given below :
      • GPIO_0 = Pass indication of Channel 1
      • GPIO_1 = Pass indication of Channel 2
      • GPIO_2 = Sync information
      • GPIO_4 = Pass indication of Channel 3
      • GPIO_5 = Pass indication of Channel 4
    • Also, using INTB for LOCK indication.

    I want to know the enumeration sequence of deserializer to serializer link establishment.

    If there is any automatic enumeration / sequence of actions happening between the serializer and de-serializer, it would be easy for us to understand the link establishment if you let us know.

    Also, if anything needs to be done apart from this automatic enumeration / sequence of actions with the serializer and de-serializer, it will be most helpful for us!!

    We show some system initialization sequencing on the device datasheet. For example, section 9.2.2 of 962 datasheet.

    If the serializer on the imager is 913A/933, you would need to strap 962 into either RAW12 LF mode, or RAW12 HF mode.
    If the serializer on the imager is 953, you should trap 962 into CSI-2 mode. See datasheet section MODE Pin section.


    GPIO settings, you would have to program the 962 device registers through I2C.
    See section 7.4.11 GPIO support
