noise of DCS1800 is severe. Therefore, the customer can choose the filter capacitance according to the 

test results. 

The position of the RF filter capacitor on the PCB should be as close to the audio device or the audio 

interface as possible, and the layout should be as short as possible. The filter capacitor should be first 

passed before reaching other connection points. The position of the antenna should be as far as possible 

from the audio component and audio layout to reduce radiation interference. The power supply layout and 

audio layout should not be parallel, and the power supply cord should be as far as possible from the audio 

layout. Differential audio layout must follow the routing rules for differential signals. 

3.10.4    Microphone Interface Circuit 

The MIC_P/MIC_N has provided the ECM bias voltage internal, and there is no need to add the bias 

circuit external. The microphone reference circuit is shown in the following figure:
