Product Description

The NX321 XO series is a high performance

CMOS crystal oscillator family with very

low jitter performance. It supports various

options including wider frequency range,

2.5V/3.3V voltage, and various stabilities.

It is designed to meet the clock source

specifications for communication systems,

and other high performance equipment.

Applications

• Networking systems

*Extended high frequency power decoupling is recommended (see test circuit for minimum

recommendation). To ensure optimal performance, do not route RF traces beneath the

package.

• Servers and storage systems

• Profession video equipments

• Test and measurement

• FPGA/ASIC clock generation

Notes:

1. Stability includes all combinations of operating temperature, load changes, rated input (supply) voltage changes, initial calibration tolerance (25°C),

aging (1 year at 25°C average effective ambient temperature), shock and vibration.

2. Phase jitter typical value is depending on output frequencies.
