Abstract: An apparatus includes an oscillator circuit and a low-pass filter circuit coupled to an output terminal of the oscillator circuit. The apparatus further includes a first digital signal generator coupled to at least one of an output terminal of the low-pass filter circuit and the output terminal of the oscillator circuit and a second digital signal generator coupled to at least one of the output terminal of the low-pass filter circuit and the output terminal of the oscillator circuit. The second digital signal generator generates a second digital clock signal based on a non-differential signal output of the oscillator circuit. The apparatus further includes a radio frequency interference (RFI) detection circuit coupled to the first digital signal generator and the second digital signal generator. The RFI detection circuit detects RFI associated with the non-differential signal output of the oscillator circuit.
