HCMOS Crystal Oscillator

The XUH is an HCMOS Crystal Oscillator with 300fs typical phase jitter over 12kHz to 20 MHz 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.
