The XPRESSO range of fully configurable VCXOs utilizes a
family of proprietary ASICs developed for noise reduction to
provide oscillators with noise levels comparable to traditional
bulk-produced quartz and SAW-based VCXOs.
XPRESSO VCXOs are low-cost, low-noise, have a wide
frequency range, excellent ambient performance and are
available on very short leadtimes. All XPRESSO VCXOs are
100% final tested .
