DS90UB954-Q1: ds90ub954-q1, On setting Virtual Channel ID

Part Number: DS90UB954-Q1

I would like to set up the Virtual Channel as Above.  Do you have reference register Software setting for this. I read on the datasheet seems like I need to set up 0x72, 70 and 71. But I not too sure how to set up)

    Hi,

    Sorry the picture I attached do not appear above :  The above Pic is from DS90UB954-Q1 datasheet,  Pg 44 , 7.4.20.1,  Example 1.

    is the setting up of 2 camera image sensor to port 0 and Port 1 of 954 with output CSI-TX

    Hello Lee,

     

    Could you clarify which serializer you’re using?

    Assuming you’re using the 935/953 you would only need to set register 0x72 to the virtual channel ID you’d want. You would do this for each RX port:

     Mine serializer  is 953,,

    0x72 register is to Remapping for Both  incoming RX0 and RX1  two  ports?

    My 2 sensors, One attached to RX Port 0 and 1 attached to RX Port 1 of 954 . Both sensors have same Virtual Channel ID 0 (just like the example 1 in yr datasheet).

     

    How Do I set 0x72 as Both have same Virtual Channel ID

    Hello Leong,

    That is correct. However, 0x72 is port specific and you would need to specify your port that you're remapping to.

    To set a Virtual Channel ID 0 for both Ports and remap them to the ID's 0 and 1, you would do the following:

    board.WriteI2C(DES_ADDR, 0x4C, 0x01) # This writes to Port 0

    board.WriteI2C(DES_ADDR, 0x72, 0x00) # This remaps the Virtual Channel ID 0 to Port 0

    board.WriteI2C(DES_ADDR, 0x4C, 0x12) # This writes to Port 1 of the deserializer

    board.WriteI2C(DES_ADDR, 0x72, 0x01) # This remaps the Virtual Channel ID 1 to Port 1

    Best,
