NIPPON PRECISION CIRCUITS INC.—1 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-har- monic oscillator devices. The crystal oscillator circuit has a built-in thin-film feedback resistor with good tem- perature characteristics and built-in capacitors with excellent frequency response, resulting in a stable 3rd- order overtone oscillator with only the connection of a crystal element.
