Example of an RC oscillator. Typical formula for oscillator frequency:
f
TIMING COMPONENTS LIMITATIONS
The oscillator frequency is mainly determined by R
influence of the forward voltage across the input protection diodes on the frequency. The stray capacitance C2 should be kept as small as
possible. In consideration of accuracy, C
