resistor-capacitor (RC) network.
An external resistance value of 15 k is recommended for oscillator operation with an
external RC network. The minimum resistance value to ensure operation is 10 kThe
typical oscillator frequency is estimated from the values of the resistor (R in k) and
capacitor (C in pF) elements using the following equation:

XIN pin and the printed circuit board must be included in the estimation of the oscillator
frequency.
