For a long time, the process of specifying and selecting oscillators for your
equipment designs has involved balancing technical demands and practical
considerations – in terms of physical performance, purchase cost,
and delivery time.
Not any longer!
The revolutionary new XpressO crystal oscillator family
from Fox provides a wider range of options, with fewer
compensating factors, shorter lead times, and reduced
pricing. Instead of being faced with crucial tradeoffs in
cost, performance, or delivery times, you can have
virtually the best of all worlds in one package.
If an oscillator can't deliver the performance you need in your design, it doesn't matter
how much it costs. But Fox XpressO oscillators with patented new technologies
(including
proprietary ASICs with noise reduction silicon architectures and proven production tech-
niques) deliver accurate performance over an extremely wide range of parameters – all at
a lower cost than conventional oscillators! Call today to compare XpressO's low pricing
for the following performance options:
The exact frequency you need, from 0.750 MHz to 1.350 GHz
Stabilities as tight as ±20 ppm
Low jitter and phase noise characteristics to meet your toughest needs*
Choice of HCMOS, LVDS, and LVPECL versions for both XO and VCXO product families
3.3 V available as standard
Choice of 7 x 5 mm and 5 x 3.2 mm package sizes
Specifying the optimum oscillator for your design is only half the battle. Getting it delivered
in time to meet the most pressing customer deadlines for engineering prototypes or full
production models – without technical compromise and without paying a premium – can
be the difference between a profitable contract and a lost opportunity.
This is where XpressO really lives up to its name, with:
Next day shipment of samples for prototyping
Mere days for lead times on production quantities
A new pricing structure that, unlike conventional
oscillators, won't penalize you for requesting quick
turnaround on unique frequencies
Who says
you can't have it all
?
Great for your designs.
Great for your business, too!

Characteristics
Unlike programmable oscillators, the
jitter and noise characteristics of
XpressO configurable oscillators are
comparable to or better than those of
fixed frequency oscillators in virtually
all applications. You can choose the
