32KHz clock radiation noise issues of i.MX6D.

[takashitakahash]

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.

Hi Takahashi

1. radiaton issues are solving proper board design: layout, filtering,

shielding and well dscribed in common electronic design resources.

Please create service request for obtaining  MX6 SDP EMI report.
