Manufacturer: Microchip Technology

Overview: MX55/57 Low Jitter Crystal Oscillator.

Download the MX57 datasheet PDF. This datasheet also includes the MX55 variant, as both parts are published together in a single manufacturer document.

General Description

The MX55/MX57 product line is an ultra-low jitter family of industry standard crystal oscillators (XO) designed to maximize performance in networking, storage, server, and telecommunications equipment.

The MX55 employs a space-saving 3.2 mm x 5 mm package, while the MX57 is in a 5 mm x 7 mm package.

These devices meet ±50 ppm total stability across –40°C to +85°C operating temperature range, using proven high reliability assembly methods that improve long term reliability and minimize aging drift compared to traditional XO assembly processes.
