Note
A limiting resistor is required when these ceramic resonators are used (refer to the following figure). When
other recommended resonators are used, the limiting resistor is not necessary.
Caution The oscillator constant is a reference value based on evaluation in specific environments by the
resonator manufacturer. If the oscillator characteristics need to be optimized in the actual
application, request the resonator manufacturer for evaluation on the implementation circuit.
Note that the oscillation voltage and oscillation frequency merely indicate the characteristics of
the oscillator. The internal operation conditions of the
PD17240, 17241, 17242, 17243, 17244,
17245, and 17246 must be within the specifications of the DC and AC characteristics.
