Note) The output frequency is determined by the arithmetic (frequency division) expression of a frequency input to XTALIN.

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.

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.
