Chapter 4. FUNCTIONAL DESCRIPTION
Clock Generator
The GMS36/37XXX series has an internal clock oscillator. The oscillator circuit is
designed to operate with an external ceramic resonator. Internal capacitors are
available at kHz version. Oscillator circuit is able to organize by connecting
ceramic resonator to outside.
* It is necessary to connect capacitor to outside in order to change ceramic resonator,
you must refer to a manufacturer`s resonator matching guide.
