Overview

The 5028 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 5028 series can be used to realize ultra miniature, ultra low voltage crystal oscillators.

*1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscillator frequency band is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.
