Part Number: AWR1243

HI：

I have to use two AWR1243 for cascade , but the processor has only one MIPI CSI2 interface. i do not konw how can i connect them?

Hi,

Could you please share more details about your cascade board hw architecture?

Thank you
Cesar

In my design we use two Awr1243, one is master the other is slave. The processor can get the AD data from these Awr1243 in MIPI CSI2 interface. The question is the Processor has only one MIPI CSI2, how to connect to two Awr1243?

Hello,
If you want to capture data from both the AWR1243 devices to a single CSI port of the processor you would have to use some kind of 2:1 CSI bridge. We have not tried this but I found one such FPGA product (www.latticesemi.com/.../2Inputto1OutputMIPICSI2CameraAggregatorBridge.aspx).

Best would be to use a processor which supports 2 CSI inputs, like the TDA processors from TI.

Vivek
