Dear community.

 

Our customer has question below.

32KHz external clock sources of radiation noise (EMI) can not clear the EMI request standard for their customer

(It is a harmonic  of 32KHz is a problem of GPS band. and Even if  switch to the internal oscillator  NG too. ).

 

Question

1,Would you please advise how to reduce radiation noise of 32KHz.(Have you ever become a problem in the past?)

2,Can stop the 32 KHz clock (including internal oscillator too).

  Or , Is it possible to Gate a 32KHz clock immediately after the oscillation circuit?
Thank you,
Best Regards.
T.Takahashi
