Part Number: DS90UB935-Q1

Hello,

may I help you ?

Now, I have a problem:  deserializer is DS90UB934-Q1,serializer is DS90UB935-Q1. the issue is: can not creater I2C link from deserializer to serializer, because can not find the slave ID of serializer.

Only can read &write of deserializer of DS90UB934-Q1.

waiting for your support,thanks .

  • Hello,

    First can you confirm the MODE strappings for both 934 and 935 devices? Also can you confirm the PCLK rate?

    Thanks,

    Casey

    Hello,

    Any update on the above questions?

    Thanks,

    Casey 

  • In reply to Casey McCrea:

    sorry,Today later I will check it .

  • In reply to Casey McCrea:

    1.the mode strapping is  coax raw10.

    2.pclk=96.2 

    BTW,now I will try new deserializer DS90UB954+ serializer 935  or 953, can you supply register for estblising I2c link between deserializer and serializer (slave including image sensor &ISP )

    thanks.

    Hello,

    For 935 you must ensure that the PCLK and CSI clock have a certain ratio in order for it to work properly. This app note should give all relevant configurations needed to enable DVP mode for 935 to work with 934: 

    For 954 the situation is different. You should strap both devices for synchronous CSI-2 mode and then they will automatically link without any special configuration. Init code for image sensor and ISP would come from the sensor vendor.

    Best Regards,
    Casey
