(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 27.0000MHz, 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) This parameter represents lower and upper limit voltages at the Schmitt trigger input PIN having hysteresis characteristics shown in figure below. The
width requested by these differences is assumed to be a hysteresis width.
