IDT XO HCMOS Crystal Oscillator
XUH
DATASHEET
Description
The XUH is an HCMOS crystal oscillator with 300fs typical
phase jitter over 12kHz to 20MHz bandwidth. Available in a
wide frequency range from 0.016MHz to 167MHz, the IDT
XUH series crystal oscillator utilizes a family of proprietary
ASICs, with a key focus on noise reduction technologies.
The 4th order Delta Sigma Modulator reduces noise to the
levels that are comparable to traditional bulk Quartz and SAW
oscillators. With short lead-time, low cost, low noise, wide
frequency range, excellent ambient performance, the XUH is
an excellent choice over the conventional technologies. The
XUH has stabilities as tight as ±20ppm with extremely quick
delivery for both standard and custom frequencies

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the XUH. 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.
