Description
WF5028 series 0.8V operation Crystal Oscillator Module ICs
OVERVIEW
The WF5028 series are miniature crystal oscillator module ICs. The devices are fabricated using a proprietary low voltage process, enabling 0.8V operation. The pad layouts are selective from 3 types depending on package structures, mounting methods, which are suitable for miniature crystal oscillators. The WF5028 series can be used to realize ultra miniature, ultra low voltage crystal oscillators.
