CF5005B series High-frequency Crystal Oscillator Module ICs OVERVIEW The CF5005B series are high-frequency crystal oscillator module ICs. They are comprised of an oscillator circuit 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 frequency response, making possible a stable 3rd overtone oscillator with only the addition of a crystal element.

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 characteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.

When INHN goes HIGH, normal output is not resumed until after the oscillator start-up time has elapsed. FUNCTIONAL DESCRIPTION Standby Function The oscillator stops when INHN goes LOW.
