FOXElectronics

Fox’s Expanded Line of Custom and Standard

Frequency Oscillators…in Just Days.

Fox Redefines

Oscillator Delivery.

✓

ISO-9001

Certified

For years, Fox has been ranked as America’s preferred

oscillator/cr ystal company…b y both engineers and buyers.

But we’ve never rested on our laurels. Fox continues to

pioneer advances in cr ystal and oscillator technology,

availability and technical support…from standard products

to custom solutions. Now, Fox redefines oscillator delivery

and scheduling flexibility.

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.

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%.

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

•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

•Streamlined inventory handling and control

In every respect, JITO

-2 lets you get to market faster and more

efficiently than ever before.

Fox’s current JITO

-2 line is offered in the following ranges:

•Custom and standard frequencies from 340 kHz up to 250 MHz

•100, 50, 30, 25 PPM stability

•3.3 or 5 volts; -20 to +70°C or -40 to +85°C operating range

•Both SMD and thru-hole packaging available

•Fox quality built-in

•Total technical support from the industr y leader

•Reduced Phase Jitter - 1/3 that of competitive units

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

The JITO

-2 Phase

Jitter Advantage

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

programmed oscillators.

And in certain frequency bands, the

phase jitter characteristics of our

JITO

-2 oscillators compare favorably

to fixed frequency oscillators.

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.

If phase jitter is a critical specification

for your application, specify JITO

-2 to

be sure.

Cycle to Cycle Phase Jitter measurements on our JITO

-2 oscillators are performed

with a Tektronix TDS 784C Digital Oscilloscope using the histogram function.

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.

Typical phase jitter values for the frequency range of 50MHz ~ 250MHz are

listed below:

Quartz Crystals:

Frequencies from 32.768 kHz to 200 MHz,

standard and custom; stabilities to 5 PPM.

Oscillators:

Frequencies from 340 kHz to 250 MHz, standard

and custom; stabilities from 20 PPM to 100 PPM.

TCXOs/VCXOs:

High performance temperature- and voltage-controlled

oscillators; frequencies from 1 MHz to 40 MHz.

Crystal Filters:

Frequencies from 10.7 MHz to 90 MHz.

All Fox frequency control products are 100% tested, offered in a

variety of surface mount and thru-hole configurations, and are

available directly from Fox or off the shelves of our very well

stocked national distribution network.

When it comes to frequency control, why trust your products

to anyone less than Fox? It always pays to go with the leader.
