Fox Electronics

Fox Electronics is USA’s main supplier of high-precision, high-reliability frequency control products including crystals, oscillators, TCXOs, VCXOs and filters. The applications of Fox’s products vary from wireless communications and telecommunications equipment to computers and peripherals, instrumentation, aerospace, storage, industrial, automotive, medical and military electronics.

For the last 30 years Fox’s R&D department has contributed to the company’s growth by constantly introducing technology breakthroughs that have set new standards for frequency control solutions. In the last few years, Fox’s patented compact XpressO line of configurable oscillators has given design engineers new levels of delivery flexibility, shorter lead-times, and reduced costs – without compromising the very highest levels of electrical performance. They offer a wide range of frequencies, stability as tight as +20 ppm, very low jitter and phase noise.

Regarding low-current oscillators, Fox Electronics has lowered minimum power requirements from the previous standard of 20 mA to as little as 2.5 mA, in a footprint as small as 3.2 mm x 2.5 mm. This product line is extremely suitable for battery-powered and portable/wireless devices where minimizing power consumption in ever-smaller devices is what matters.
