Overview

The 5055A series are miniature crystal oscillator module ICs supported 20MHz to 40MHz fundamental oscillation.
The oscillator circuit stage has voltage regulator drive, significantly reducing current consumption and crystal drive current, compared with existing devices, and significantly reducing the oscillator characteristics supply voltage dependency. The lowest current consumption class in the industryis realized as the crystal oscillation modules IC of CMOS output. The pad layout is arranged for flip chip mounting, these devices are ideal for miniature crystal oscillators for the applications such as portable equipment requested small size and low consumption current.

*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.
