Why is the damping resistor is required?
• Answer :The damping resistor is used to form low-pass filter with the load capacitor and reduces the higher gain in order to suppress abnormal oscillation of high frequencies. Moreover, the IC gain is limited to provide better matching between the IC and resonator. So, unnecessary ringing decreases, thus enabling suppression of overshoot and undershoot. For details, contact a manufacturer of the oscillator used.
