* Both C1 and C2 must be 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.
