Figure 76. Typical Application with a Crystal or Ceramic Resonator
1. The relatively low value of the RF resistor, offers a good protection against issues resulting from use in a humid envi-
ronment, due to the induced leakage and the bias condition change. However, it is recommended to take this point into
account if the µC is used in tough humidity conditions.
2. For C
for high-frequency applications and selected to match the requirements of the crystal or resonator. C
ally the same size. The crystal manufacturer typically specifies a load capacitance which is the series combination of C
and C
