WF5027 series
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
I 3 pad layout options for mounting

*1. The consumption current IDD (CL) with a load capacitance (CL) connected to the Q pin is given by the following equation, where IDD is the no-load con-
sumption current and fOUT is the output frequency.
IDD (CL) [mA] = IDD [mA] + CL [pF] × VDD [V] × fOUT [MHz] × 10–3
