Description
The Fox XPRESSO-ULTRA Crystal Oscillator is a
breakthrough in configurable Frequency Control
Solutions. XPRESSO-ULTRA utilizes a family of
proprietary ASICs, designed and developed by Fox,
with a key focus on noise reduction technologies.
The 4th order Delta Sigma Modulator reduces noise to
the levels that are comparable to traditional Bulk
Quartz and SAW oscillators. The ASICs family has
the ability to select the output type and supply
voltage.
With the XPRESSO-ULTRA lead-time, low cost, low
noise, wide frequency range, excellent ambient
performance, XPRESSO-ULTRA is an excellent choice
over the conventional technologies.
