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
typical oscillator frequency is estimated from the values of the resistor (R in K ) and
capacitor (C in pF) elements using the following equation

function of the capacitor (C in pF) employed in the RC network assuming a 45 K
external resistor. For very small values of C, the parasitic capacitance of the oscillator X
pin and the printed circuit board must be included in the estimation of the oscillator
frequency.
