Note
When using the CSB1000J (1.0 MHz) made by Murata Mfg. Co., Ltd. as a ceramic resonator, a limiting
resistor (Rd = 2.2 k
) is necessary (refer to the figure below). This resistor is not necessary when using
the other recommended resonators.
Caution
The oscillator constants and oscillation voltage range indicate conditions for stable oscilla-
tion, but do not guarantee oscillation frequency accuracy. If oscillation frequency accuracy is
required for actual circuits, it is necessary to adjust the oscillation frequency of the oscillator
in the actual circuit. Please contact directly the manufacturer of the resonator to be used.
