Description
The Fox X
PRESS
O Crystal Oscillator is a
breakthrough in configurable Frequency Control
Solutions. X
PRESS
O utilizes a family of
proprietary ASICs, designed and developed by
Fox, with a key focus on noise reduction
technologies.
The 3
rd
order Delta Sigma Modulator reduces
noise to the levels that are comparable to
traditional Bulk Quartz and SAW oscillators.
The ASICs family has ability to select the output
type, input voltages, and temperature
performance features.
With the X
PRESS
lead-time, low cost, low noise,
wide frequency range, excellent ambient
performance, XpressO is an excellent choice
over the conventional technologies.
Finished X
PRESS
O parts are 100% final tested.
