If the input frequency is set to 36.8640MHz, the output frequency will be as listed above. Common to BU2285FV and BU2363FV: *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. *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. *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. BU2363FV *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 (33.8688MHz20kHz) as a measurement point. |
