XU Family of Low Phase Noise
Quartz-based PLL Oscillators
Datasheet
XU
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
memory 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.

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the device. These ratings, which are standard values for IDT
commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those
indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
