Typical Application Schematic
Note: As a good practice in any RF design, shielding around sensitive nodes can
improve the EMC performance of the application.
For achieving the best sensitivity results the following has to be kept in mind. Every
digital system generates certain frequencies (f
, e.g. the crystal frequency or a
SRC
microcontroller clock) and harmonics (N * f
) of it, which can act as interferer (EMI
SRC
source) and therefore sensitivity can be reduced.
