HCSL Crystal Oscillator

The XUO is an Ultra Precision HCSL Crystal Oscillator with 300 fs typical phase jitter over 12 kHz to 20 MHz bandwidth. Available in a wide frequency range from 16 kHz to 670 MHz, the IDT XUO 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 XUO is an excellent choice over the conventional technologies. The XUO has stabilities as tight as ±20 ppm with extremely quick delivery for both standard and custom frequencies.
