Oscillators Tout Tight Frequency Stability and Operate Over Wide Temperature Range

Mon, 11/14/2011 - 10:02am
crystal oscillator tight stabilityFox Electronics offers its XpressO XO oscillators with a tight frequency stability to ±25 ppm over the operating temperature range of -20°C to +70°C in a miniature 3.2-mm x 2.5-mm package. The new HCMOS 3.3 V FXO-HC336 is appropriate for use in a variety of applications, including microprocessor, DSP, FPGA, SONET and Ethernet environments as well as industrial controllers, test and measurement equipment, storage area networks and other applications that require the oscillator to maintain its frequency over a wide temperature range in a compact, cost-effective package. The RoHS- and REACH-compliant FXO-HC33 family is available in any frequency from 0.75 MHz to 250 MHz and offer a frequency resolution to six decimal places. XpressO crystal oscillators use a family of proprietary application specific integrated circuits (ASICs), designed and developed with a focus on noise reduction. These ASICs have the ability to enable users to select the optimum combination of output type, input voltages and temperature performance features.

The oscillators feature a tri-state enable/disable feature that allows the user to turn off the output as a way to reduce power consumption. The contacts of the FXO-HC33 series contacts are constructed with a gold over nickel termination finish and incorporate industry standard packaging, including footprint and pin-out. XpressO oscillators have reduced noise levels comparable to traditional bulk quartz and SAW oscillators by using the third order Delta Sigma Modulator (DSM). The low cost oscillators also offer extremely low jitter of less than 1 pS.

Samples are available in one to two days, with production quantities within ten working days. The oscillators come standard with Fox's patented serial identification system that ensures exceptional quality control and unique traceability of each individual part throughout the entire manufacturing process. Pricing for a FXO-HC336 ±25 ppm oscillator is $0.985 in quantities of 50,000.
