capacitor (RC) network.
An external resistance value of 45 K is recommended for oscillator operation with an
external RC network. The minimum resistance value to ensure operation is 40 KThe
typical oscillator frequency can be estimated from the values of the resistor (R in K) and
capacitor (C in pF) elements using the following equation:
