CF5018 series

2.5V 3rd Overtone Crystal Oscillator Module ICs

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.

1. 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 condi-

tions, so the oscillation characteristics of components must be carefully evaluated.
