Description
The Fox X
PRESS
O-ULTRA Crystal Oscillator is a
breakthrough in configurable Frequency Control
Solutions. X
PRESS
O-ULTRA utilizes a family of
proprietary ASICs, designed and developed by Fox,
with a key focus on noise reduction technologies.
The 4
th
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 X
PRESS
O-ULTRA lead-time, low cost, low
noise, wide frequency range, excellent ambient
performance, X
PRESS
O-ULTRA is an excellent choice
over the conventional technologies.
Finished X
PRESS
O-ULTRA parts are 100% final
tested.
