CF5015 series
2.5V Operation Fundamental Frequency
Crystal Oscillator Module ICs
OVERVIEW
The CF5015 series are 2.5V operation crystal oscillator ICs. They are available for frequencies up to 60MHz.
The product lineup consists of AL
×
series for 2.5V exclusive use and BL
×
series compliant with 2.5V to 5V.
The built-in oscillator capacitor of AL
×
series is large, so that AL
×
series contribute to improve the frequency
stability. For the BL
×
series, the current consumption and drive level reduced so that they can realize the char-
acteristics easier to design small-sized crystal oscillators. The oscillator circuit of each version is simply con-
structed, so that it can realize the crystal oscillator with excellent phase noise characteristics. Even if the valued
characteristics differ due to the application or the purpose, the selecting from these series for different purposes
allows the optimization.

*1. The recommended oscillation frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscil-
lator 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.
