High-frequency Crystal Oscillator Module ICs
OVERVIEW
The CF5005B series are high-frequency crystal oscillator module ICs. They are comprised of an oscillator cir-
cuit and output buffer optimized for operation at 125 to 165MHz. The crystal oscillator circuit has a built-in
thin-film feedback resistor with good temperature characteristics and built-in capacitors with excellent fre-
quency response, making possible a stable 3rd-harmonic oscillator with only the addition of a crystal element.

1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the
oscillator frequency band is not guaranteed. Specifically, when used at high frequencies, the characteristics can vary greatly due to crystal char-
acteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.
