Crystal consideration
The crystal connected to the VRS51C1100 oscillator
input should be of a parallel type, operating in
fundamental mode.
The following table provides suggested capacitor and
resistor feedback values for different operating
frequencies.
Note: Oscillator circuits may differ with different
crystals or ceramic resonators in higher oscillator
frequencies.
Crystals or ceramic resonator characteristics vary from
one manufacturer to the other.
