Description
The XU devices are low phase noise quartz-based PLL oscillators
supporting a large range of frequencies and output interface
types. These devices are designed to operate at three different
power supplies and are available in multiple package sizes as well
as temperature grades.
With a patented one-time program (OTP) allowing for infinite
memo
ry shelf life, the XU devices can be programmed to generate
an output frequency from 16kHz to 1500MHz with a resolution as
low as 1Hz accuracy. The configuration capability of this family of
devices allows for fast delivery times for both sample and large
production orders.
