DS90UB933-Q1: Does it support serialization and transmission of I2S?

Other Parts Discussed in Thread: DS90UA101-Q1, DS90UA102-Q1

Hi team，

Hope you are doing well！

1. My customer said that UB933/934 is used on the market to implement I2S serialization and transmission, but I did not see such instructions in the datasheet. Can you provide a solution for use?

2. Are there any suitable serializer recommendations? Requirements are as follows:

  • The serializer input is a 2MP camera
  • At the same time, serialize the I2S of MIC

  • +1

    Hi Guohai, 

    We do not include information on implementing I2S in the DS90UB933 datasheet and this was not tested. It may be possible if the signaling is similar to LVDS. Please refer to this Thread for more details.

    Alternative options for I2S transmission can be the DS90UB935/DS90UB953. More details can be found in this Thread and in this App Note on I2S implementation. 

    Additionally, DS90UA101-Q1 and DS90UA102-Q1 is a serializer deserializer pair designed for audio transmission. 

    Best,

    Zoe
