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.
FEATURES
I 2.25 to 2.75V operating supply voltage range
I 30MHz to 80MHz oscillation frequency range
(varies with version)
I – 40 to 85°C operating temperature range
I Oscillation capacitors CG, CD built-in
I Inverter amplifier feedback resistor built-in
I Standby function

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.
