Output at 27MHz input is shown above. Jitter is value when using Time interval analyzer with 10000 sampling. ∗1) Low and high limit voltage in the schmitt trigger input Pin having hysteresis features shown in ∗3 diagram. ∗2) Time that output takes to stabilize in the specific frequency range after the power supply reaches to 3.0V. ∗3) Make reference to the diagram. |
