Note
If using Murata’s CSB1000J (1.0 MHz) as the ceramic resonator, a limited resistor (Rd = 2.2 k
Ω
) is required
(see figure below). If using any other recommended resonator, no limited resistor is needed.

Caution The oscillation circuit constants and oscillation voltage range indicate conditions for stable
oscillation, 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
resonator in the circuit. Please inquire directly to the maker of the resonator for data as needed.
