Definition: duration tSU between the application of the supply voltage to the oscillator and the time when the RF output signal of desired frequency controlled by the quartz resonator fulfils the following specified conditions:

  1. for quasi-sinusoidal waveforms, the signal envelope is 90 % of the steady-state peak-to-peak amplitude;
  2. for pulse waveforms, the output pulse sequence is periodical near the steady-state frequency while its low level VLO remains below VOL and its high level VHI exceeds VOH permanently, where VOH and VOL are defined by the applicable logic family
