5027 series

SEIKO NPC CORPORATION —1

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.
