WF5027 series
SEIKO NPC CORPORATION —1
Crystal Oscillator Module ICs
OVERVIEW
The WF5027 series are miniature crystal oscillator module ICs. The oscillator circuit stage has voltage regula-
tor drive, significantly reducing current consumption and crystal current, compared with existing devices, and
significantly reducing the oscillator characteristics supply voltage dependency. There are 3 pad layout package
options available for optimized mounting, making these devices ideal for miniature crystal oscillators.
FEATURES
I
Wide range of operating supply voltage: 1.60 to 3.63V
I
Regulated voltage drive oscillator circuit for reduced
power consumption and crystal drive current
I
Optimized low crystal drive current oscillation for
miniature crystal units
