※1 Period-Jitter 1σ
This parameter represents standard deviation (=1σ) on cycle distribution data when the output clock cycles are sampled 1000
times consecutively, with the TDS7104 Digital Phosphor Oscilloscope of Tektronix Japan, Ltd.
※2 Period-Jitter MIN-MAX
This parameter represents a maximum distribution width on cycle distribution data when the output clock cycles are sampled
1000 times consecutively, with the TDS7104 Digital Phosphor Oscilloscope of Tektronix Japan, Ltd.
※3 Output Lock-Time
This parameter represents the elapsed time to reach a voltage of 3.0 V after power supply turns ON and after the system is
switched from power-down to normal operation state, or after the output frequency is switched and is stabilized.
If the input frequency is set to 12.000000MHz, the output frequency will be as listed above.
