Part Number: DS90UB953-Q1
Other Parts Discussed in Thread: AWR1243

Hello,

Can the MIPI CSI2 data from AWR1243 radar chip be transmitted by this chip?

Thanks,

    Hello ,

    Yes, the ADC data from the AWR1243 device can be sent out on the MIPI CSI interface. You can find CSI pin details in the datasheet and also the mmwave DFP package provides the API details to configure CSI interface.

    Regards,

    Hello Vivek,
    Thank you for your quick reply.

    The control I/F of AWR1243 is SPI but DS90UB953 can transmit only I2C I/F.
    I think I should use I2C to SPI converter and AWR1243 can be controlled through DS90UB953 from HOST.
    Is it correct?

    I concern the delay time will be increase and if it will not meet the specification of AWR1243 I/F because the communication speed of I2C is slower than SPI.
    What do you think about?

    Thanks,
    Hirosada

    Hello Hirosada San,

    You are right, to use the SPI interface you need to use a I2C to SPI converter.

    Over DS90UB953 the communication over I2C backchannel will be very slow and the timing would be unpredictable. If you are not doing much dynamic configuration , basically configuring the device once and then just getting the CSI data , it should not be an issue.
