(Note 1) 1 In the case of exceeding Ta = 25°C, 6.3mW to be reduced per 1°C
(Note) Operating is not guaranteed.
(Note) Power dissipation is measured when the IC is mounted to the printed circuit board.
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.

(Note 3)
(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.

σ
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.
