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.

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.

FUNCTIONAL DESCRIPTION
Standby Function
When INHN goes LOW, the oscillator stops and the oscillator output on Q becomes high impedance.
Power-save Pull-up Resistance
The INHN pull-up resistance changes in response to the input level (HIGH or LOW). When INHN goes LOW
(standby state), the pull-up resistance becomes large to reduce the current consumption during standby.
