Redefining Oscillator
Delivery… Again!
Meeting Today’s Time-to-Market Pressures
Meeting Today’s Build-to-Order (BTO)
Flexible Scheduling Needs
The ability to provide custom and standard frequency oscillators
in days rather than weeks translates to tremendous benefits in
terms of production scheduling flexibility. Only Fox’s JITO®-2
program provides all this:
• Changes in orders allowed up to ship date
• Flexibility to cancel orders up to 10 days prior to ship
date at no cost

with JITO -2 …Just-In-Time Oscillators :
Custom and Standard Frequency
Oscillators in Days!
The new JITO®-2 (Just-In-Time Oscillators®) line represents Fox’s
latest contribution to helping buyers and engineers alike meet
the increasing pressure of bringing new designs and products
to market faster and more efficiently. This new line of crystal
oscillators cuts the industry standard lead time of 10 weeks
down to just 10 business days or less for custom or standard
frequency oscillators.
• Unlimited upside order flexibility
• Samples and prototypes shipped immediately
These JITO®-2 advantages yield increased user benefits, including:
• No stocking or forecasting required
• JIT scheduling flexibility
• Ideal for build-to-order manufacturing
• No part shortages
JITO®-2 represents the latest Fox response to urgent marketplace
pressures. Engineers need custom frequencies as quickly as
possible to test and prove their prototypes. Production people
need to know that custom frequency products can be accessed
quickly without holding up their line. And buyers have to ensure
they can satisfy both engineering and production needs. The
JITO®-2 line provides a total solution to those requirements by
cutting industry standard lead times by an average of 90%.
• Streamlined inventory handling and control
In every respect, JITO®-2 lets you get to market faster and more
efficiently than ever before.
®
JITO -2 today…and tomorrow
Fox’s current JITO®-2 line is offered in the following ranges:
JITO®-2 is Fox’s answer to the phenomenal response we received
from engineers and buyers to our initial JITO® program. The
much-expanded and enhanced line features a wider range of
frequencies, stabilities, operating temperatures and packages,
plus greater flexibility in specification changing and scheduling.
As JITO®-2 expands, we’ll post product information on our
website; www.foxonline.com. Check it, contact your local Fox
representative, or call direct, 888-GET-2-FOX.

The JITO -2 Phase
Jitter Advantage
Phase Jitter Measurements at Fox Electronics
Cycle to Cycle Phase Jitter measurements on our JITO®-2 oscillators are performed
with a Tektronix TDS 784C Digital Oscilloscope using the histogram function.
Phase Jitter has long been recognized as
one of the most critical and defining
parameters in the design and application
of oscillators. Fox JITO®-2 Just-In-Time
Oscillators ® meet the need for more
tightly controlled phase jitter. As
detailed in the technical data below,
JITO®-2 oscillators offer a 67% reduction
in phase jitter over competitive
With the trigger set at the midpoint of the rising edge, a histogram of the
horizontal deviation of the first rising edge from the trigger point is constructed.
The peak to peak distribution and standard deviation (Sigma or RMS) is derived
from this histogram. This is the "measured" cycle to cycle phase jitter, peak to
peak and RMS. The same measurement is then taken at the trigger point to
determine "trigger phase jitter" (typically 60 ~ 80pS p-p/10 ~ 13pS RMS).
The trigger phase jitter is then subtracted from the measured phase jitter one
cycle out to determine cycle to cycle phase jitter, peak to peak and RMS.
Typical phase jitter measurements listed here are based on subtracting the
lesser, 60pS p-p/10pS RMS, value from all measured values.
programmed oscillators.
And in certain frequency bands, the
phase jitter characteristics of our
JITO®-2 oscillators compare favorably
to fixed frequency oscillators.
Typical phase jitter values for the frequency range of 50MHz ~ 250MHz are
listed below:

The dramatically reduced phase jitter
of Fox JITO®-2 oscillators can make your
systems less prone to the introduction of
bit errors with microprocessors and
increase the reliability of any data
sensitive application.
