CF5011 series

NIPPON PRECISION CIRCUITS INC.—1

1.8V Crystal Oscillator Module ICs

OVERVIEW

The CF5011 series are low-voltage crystal oscillator module ICs that operate at 1.8V. The crystal oscillator cir-

cuit and output buffer employ a low-voltage CMOS process operating at 1.8V. The crystal oscillator circuit has

a built-in thin-film feedback resistor with good temperature characteristics and built-in capacitors with excel-

lent frequency response, making possible a stable 3rd-harmonic oscillator with only the addition of a crystal

element.
