WF5025 series
Crystal Oscillator Module ICs
OVERVIEW
The WF5025 series are miniature crystal oscillator module ICs. They feature a damping resistor RD matched to
the crystal's characteristics to reduce crystal current. The pad layout is arranged for flip chip mounting, which
gives the pattern design more flexibility, even for mounting ultra-miniature crystal oscillators that provide
almost no space for wiring patterns. They support fundamental oscillation and 3rd overtone oscillation modes.
The WF5025 series can be used to correspond to wide range of applications.

*1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscil-
lator frequency band is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the
oscillation characteristics of components must be carefully evaluated.
*2. The WF5025BL1 has a higher maximum operating frequency, hence the negative resistance is also larger than in the WF5025AL× devices.
Note. These versions in parentheses ( ) are under development. Please ask our Sales & Marketing section for further detail.

*2. Oscillator stop function is built-in. When INHN goes LOW, normal output stops. When INHN goes HIGH, normal output is not resumed until after the
oscillator start-up time has elapsed.
