Product Description
The UX31/UX321 XO series is a high
performance CMOS crystal oscillator family
with ultra low jitter performance. It supports
various options including wider frequency range,
1.8V/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.
*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.
