CCS/TDA2P-ACD: TDA2P Performace Evaluation

CCS/TDA2P-ACD: CSI 2 interface with AWR1243P

Dear TI Experts

I'd like to use TDA2PX with  two AWR1243P through two CSI interface~

But from the datasheet, one CSI interface only supports 2 data line, the data rate is not enough for us()

Can you help advice one processor, that can be used with AWR1243P,  and has two CSI interface of 4 data each?

Thank you very much

    Hello,

    Unfortunately, this family of devices (J6/TDA2x) only supports 2 data lanes on the secondary CSI. We have a newer processor (J7/TDA4) that has 4 data lanes on both CSI channels. 

    What throughput are we talking here? Is 2x1.5Gbps not enough on the secondary CSI? 

    Thanks,

    Alex

    Dear Alex

    Than you~

    Customer plans to use two AWR1243P  cascading，the raw data of AD needs to be sent to TDA2Px processor through CSI2 interface.

    The transmission speed of CSI_2 cannot  reach  the four-channel recieve rate  that we desired under the condition of 37.5M sample rate~

    When two  AWR1243P used with TDA， which TDA do you recommend?

    The reference design is using TDA2HGB with FPGA to provide CSI Interface

    Hi Qianqian,

    Sorry for delayed response

    In the current design (TDA2x + FPGA), would you know the maximum data rate being used? Based on that we can evaluate the required number of lanes and the device that could be used.
