4.5 CLOCK AND TIMING CHARACTERISTICS
Subject to general operating conditions for V
4.5.1 Crystal Oscillator
The Device internal clock is supplied from a crystal oscillator. All the information given in
this paragraph are based on characterization results with specified typical external
components. In the application the load capacitors have to be placed as close as possible to
the oscillator pins in order to minimize output distortion and start-up stabilization time. Refer
to the crystal manufacturer for more details (frequency, package, accuracy...).
