TDA4VM: TDA4VM Internal Operating clock question for 1.875Ghz

Hello Expert,

Small question for TDA4VM internal operating clock used.

During EMI Testing, only one point failure has been occurred from 1.875Ghz, That's why i'm asking for the internal operating clock.

Please check whether the 1.875Ghz frequency used or not in TDA4VM internally.

Thanks.

    That would not be a normal operating point. The Display Sub System PLLs do not have a "typical" target frequency as they are tied to the details of the display system. Otherwise, there is no obvious candidate for 1.875GHz.

    I assume that you do not see 1.875GHz in the ambient?
