Fort Myers, Fla. − Fox Electronics, an IDT company, now offers its XpressO temperature compensated crystal oscillator (TCXO) with tighter stabilities in custom frequencies up to 250 MHz. Available in ten working days or less, the XpressO-TC HCMOS TCXOs are available with stabilities of +/-1.5 ppm from -40 degrees C to +85 degrees C as well as down to +/-1 ppm from 0 degrees C to +70 degrees C.
The TCXOs expand Fox's FXTC-HE73 series that meets the humidity, shock and vibration requirements of MIL-STD-202. They are suitable for applications requiring very tight stability over temperature and low jitter, including medical monitoring and measurement, telecommunications and networking as well as military communications.
Because these TCXOs surpass the typical 50-MHz to 60-MHz frequency range of traditional TCXOs, they offer a significant performance advantage with custom frequencies that can be specified up to 250 MHz, said the company.
Fox's proprietary ASIC technology, with a 3rd order Delta Sigma Modulator (DSM), enables XpressO oscillators to significantly reduce noise to levels comparable with traditional bulk quartz and SAW oscillators, said the company. It also enables the selection of output type, input voltages and temperature performance of the oscillator.
"With over 30 million units shipped, our XpressO oscillators continue to provide our customers with the benefits they need to meet the price and performance demands of their industries," said E.L. Fox., Jr., president, in a statement. "These enhanced versions of the TCXOs, with stabilities as tight as +/-1 ppm over custom frequencies to 250 MHz, offer more design options for electronic device manufacturers."
In addition, the XpressO-TC includes Fox's serial identification system that ensures quality control and unique traceability of each part throughout the entire manufacturing process, according to the company.
Availability: Samples are available in one to two days with production quantities in ten working days.
