5027 series
Crystal Oscillator Module ICs
OVERVIEW
The 5027 series are miniature crystal oscillator module ICs. The oscillator circuit stage has voltage regulator
drive, significantly reducing current consumption and crystal current, compared with existing devices, and sig-
nificantly 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.
