*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.
Product Description
The UX71/UX701 XO series is a high
performance CMOS crystal oscillator family
with ultra low jitter performance. It supports
various options including wider frequency
range, 2.5/3.3 voltage, various stabilities,
and different package sizes. It is designed
to meet the clock source specifications for
communication systems with 40G or 100G
interfaces, and other high performance
equipment.
