NPC CF5012 Low-current consumption crystal oscillator module ic Datasheet

CF5012 series
Low-current Consumption Crystal Oscillator Module ICs
OVERVIEW
The CF5012 series are low-current consumption 3rd-harmonic crystal oscillator module ICs. Internal circuit
optimization means these devices have reduced current consumption in comparison with our existing 3rd-harmonic oscillator devices. The crystal oscillator circuit has a built-in thin-film feedback resistor with good temperature characteristics and built-in capacitors with excellent frequency response, resulting in a stable 3rdorder overtone oscillator with only the connection of a crystal element.
