If the input frequency is set to 36.8640MHz, the output frequency will be as listed above. (Note 1) Period- Jitter 1σ This parameter represents standard deviation ( 1 ) on cycle distribution data at the time when the output clock cycles are sampled 1000 times consecutively with the TDS7104 Digital Phosphor Oscilloscope of Tektronix Japan, Ltd. (Note 2) Period-Jitter MIN-MAX This parameter represents a maximum distribution width on cycle distribution data at the time when the output clock cycles are sampled 1000 times consecutively with the TDS7104 Digital Phosphor Oscilloscope of Tektronix Japan, Ltd. (Note 3) Output Lock-Time The Lock-Time represents elapsed time after power supply turns ON to reach a 3.0V voltage, after the system is switched from Power-Down state to normal operation state, or after the output frequency is switched, until it is stabilized at a specified frequency, respectively. (Note 4) Make measurements with settings of SPAN to 100kHz, RBW to 1kHz, and VBW to 100Hz taking the middle point between (54.0000MHz±20kHz) and (33.8688MHz±20kHz) as a measurement point. |
