Recommended sample circuit for the main system clock when the CSB1000J manufactured by Murata Mfg.
is used
When a crystal is used for the subsystem clock (T
A
= -10 to +60

C)
Caution The oscillation circuit constant and oscillation voltage range indicate the conditions to settle the
oscillation, not to guarantee the accuracy of the oscillation frequency. When an accuracy
oscillation frequency is needed for the implemented circuit, the oscillation frequency of the
resonator should be adjusted on the circuit. Ask the manufacturer of the resonator you use.
