IWR1642: Acquisition Times, Reporting Times, Level of Certainty

Part Number: IWR1642
Other Parts Discussed in Thread: AWR1642

Hi team,

What are the acquisition and reporting times of the IWR1642 and the associated certainty? Please advise if there's somewhere I can look to find this information.

Also, is the only difference b/t the AWR1642 & IWR1642 the supported temp range & qualification testing that's done?

Thank you.

    The acquisition/ reporting times /certanty depends on the configuration setting. 

    Acquisition time can be got from the chirp configuration: the ramp time, idle time, inter-chirp time, number of chirps and number of frames, etc. 

    Reporting time can be got by programming GPIO pins signaling the start and finish of the data processing. We don't have data for out-of-bo demo but if you need more details we can get you help on how to setup GPIO pins.

    IRW1642 doesn't have CAN-FD but ARW1642 does.

    Regards,

    Michelle

    Thank you Michelle.

    I understand there are several factors that play into this, but can you advise what order of magnitude range could be achieved/expected?

    Please check this document:
    www.ti.com/.../swra553

    Section 3 shows typical chirp configuration for different range. It depends on the system setup. USRR and SRR can be achieved on the BOOST EVM. Longer range will require different antenna design.

    Also , this online tool will help you calculate the chirp parameters based on the application:
