CF5012 series

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.
