Oscillator Operation with an External RC Network
Figure 28. Connecting the On-Chip Oscillator to an External RC Network
Figure 28 displays a recommended configuration for connection with an external resistor-
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 kThe
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:
Figure 29 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 45 K external resistor. For
very small values of C, the parasitic capacitance of the oscillator X
circuit board must be included in the estimation of the oscillator frequency.
It is possible to operate the RC oscillator using only the parasitic capacitance of the pack-
age and printed circuit board. To minimize sensitivity to external parasitics, external
capacitance values in excess of 20 pF are recommended.
