Product Description
The NX51SB XO series is a high
performance CMOS crystal oscillator
family with very low jitter performance and
selectable output frequencies. Depending
on customers' needs, this family devices
can support up to 4 different frequencies
using the FS select pins. It supports various
options including wider frequency range,
2.5V/3.3V voltage, and various stabilities.
*Extended high frequency power decoupling
It is designed to meet the clock source
is recommended (see test circuit for
specifications for communication systems,
minimum recommendation). To ensure
optimal performance, do not route RF traces
and other high performance equipment.
