The XPRESSO range of fully configurable VCXOs utilizes a

family ofproprietary 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 .
