Oscillator (OSC)
7.3 Oscillator External Connections
Technical Data
94
In its typical configuration, the oscillator requires five external
components. The crystal oscillator is normally connected in a Pierce
oscillator configuration, as shown in
the logical representation of the internal components and may not
represent actual circuitry. The oscillator configuration uses five
components:
The series resistor (R
oscillator guidelines and may not be required for all ranges of operation,
especially with high-frequency crystals. Refer to the crystal
manufacturer’s data for more information.
