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