* Both C3 and C4 must use J rank (±5%) and CH characteristics.
(It is about the application which is not in need of high precision. Use K rank (±10%) and SL characteristics.)
(Notes) Since the circuit pattern affects the oscillation frequency, place the oscillation-related parts as close to the oscillation
pins as possible with the shortest possible pattern length.
If you use other oscillators herein, we provide no guarantee for the characteristics.
