VRS51L1050
Crystal consideration
The user should review the technical literature supplied
with the specific crystal or ceramic resonator or contact
the manufacturer to select the appropriate values for
external components.
The crystal connected to the VRS51L1050 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:
