IWR6843: Clock configuration

Tom Fisher

Part Number: IWR6843

Hi,

Our board is designed to use another MCU as the application controller and share clock signal with IWR6843.

Would you please point out where I could find the detailed document about how to configure the clock, as shown as in the above diagram?

Cheers,

Tom

Hi,

Can you please provide some more details on the clock sharing?

In the case where an external clock is used as the clock resource, the signal is fed to the CLKP pin only; CLKM is grounded. The phase noise requirement is very important when a 40-MHz clock is fed externally.

Please see table 5-5 of datasheet for specification.
