Part Number: AFE4900

Hi 

Due to board layout limitations, we have to consider putting a Buck-Boost Regulator power chip is placed in the same shield as the AFE4900, Buck-Boost Regulator's spec is attached, and its working frequency is 1.8MHz.FAN49103AUC340X.pdf
Please help to confirm whether it will affect the work of AFE4900. At present, the ECG of AFE4900 adds filter circuit, and the signal is also processed by packet. The schematic diagram of the circuit is shown in the figure below. The RLD series has 100K resistor, but there is no filtering.
