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.
