com 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.
