com OVERVIEW The CF5018 series are crystal oscillator ICs that operate from 2.
5V.
Devices are available that provide 3rd overtone oscillation in the range 30MHz to 80MHz.
They are optimized for 2.
5V operation, resulting in stable oscillator startup characteristics and output duty stability.
They feature a large reduction in chip surface area compared to existing devices, making possible the construction of small-sized crystal oscillator.

The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication.
However, the oscillator frequency band is not guaranteed.
Specifically, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.
