CF5014 series
Crystal Oscillator Module ICs
OVERVIEW
The CF5014 series are fundamental frequency crystal oscillator ICs. They are available for frequencies up to
60MHz. The chip layout is optimized, resulting in a large reduction in chip size, when compared to existing
devices.

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.
