Note) When input frequency is 14.318182MHz, output frequency is above rated value.

∗1) Period Jitter 1σ : This value is the standard deviation of an output period when using Time Interval Analyzer with 10,000 sampling.

∗2) Period Jitter MIN-MAX : This value is the max range of an output period when using Time Interval Analyzer with 10,000 sampling.

∗3) Output Lock time : This value is the time until the output clock gets stable after the power supply voltage leads to 3.0V.
