CF5016 series
1.8V Operation Fundamental Frequency
Crystal Oscillator Module ICs
OVERVIEW
The CF5016 series are 1.8V operation crystal oscillator ICs. They are available for frequencies up to 50MHz.
They employ a recently developed low-voltage process optimized for operation at 1.8V, resulting in stable
operation at low voltages while maintaining the same output duty stability of existing devices. They are ideally
suited for battery-operated electronic equipment applications where small size, low-voltage operation, and low
power dissipation are essential.

Version
1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. How-
ever, 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.
