18.1 Oscillator Circuit
18.1.3 Oscillation Stabilization Time at Power-on
The oscillator circuit comprised of a ceramic (or crystal) resonator has a finite time after power-on at
which its oscillation is instable. Therefore, create a certain amount of oscillation stabilization time
that suits the oscillator circuit used. Figure 18.1.2 shows an oscillation stabilization time at power-
on.
