Oscillator Operation with an External RC Network

Figure 59. Connecting the On-Chip Oscillator to an External RC Network
Oscillator Frequency (kHz)
Figure 59 displays a recommended configuration for connection with an external
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:
Figure 60 displays the typical (3.3 V and 25°C) oscillator frequency as a function of the
capacitor (C in pF) employed in the RC network assuming a 15 k external resistor. For
very small values of C, the parasitic capacitance of the oscillator XIN pin and the printed
circuit board must be included in the estimation of the oscillator frequency.
