Note
When the CSB1000J (1.0 MHz) manufactured by Murata Mfg. is used as a ceramic resonator, a limiting resistor
(Rd = 5.6 k
W
) is required (see the figure below). Other recommended resonators do not require such a limiting
resistor.

Caution
The oscillation circuit constants and oscillation voltage range only indicate the conditions under which
the circuit can oscillate stably, and do not guarantee the oscillation frequency accuracy. If oscillation
frequency accuracy is required in the actual circuit, it is necessary to adjust oscillation frequencies in
the actual circuit, and you should consult directly with the manufacturer of the resonator used.
