25.5 External Crystal / Resonator Connections
The connections for a crystal/resonator frequency reference are shown in the following
figures. When using low-frequency, low-power mode, the only external component is the
crystal or ceramic resonator itself. In the other oscillator modes, load capacitors (C
and feedback resistor (R
connections.
1. When the load capacitors (Cx, Cy) are greater than 30 pF, use Connection 3.
2. With the low-power mode, the oscillator has the internal feedback resistor R
