CD74HCT7046A: Any method to move the demodulation noise to higher freq.

Part Number: CD74HCT7046A

Hi Team,

Our customer is using CD74HCT7046A for an FM demodulation circuit. While the output demodulation noise is too high: around 50~60mVpp.

Is there any method to decrease the noise amplitude?

Or any method to move the demodulation noise to higher freq? Now, the noise freq is around several kHz to 20kHz.

Look forward to your response, many thanks!

Regards,

Bell
