fox electronics fox s expanded line of custom and standard frequency oscillators?n just days. fox redefines oscillator delivery. iso-9001 iso-9001 certified
for years, fox has been ranked as america s preferred oscillator/crystal company?y both engineers and buyers. but we?e never rested on our laurels. fox continues to pioneer advances in crystal and oscillator technology, availability and technical support?rom 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. meeting today s time-to-market pressures with jito -2 just-in-time oscillators : custom and standard frequency oscillators in days! meeting today s build-to-order (bto) flexible scheduling needs fox redefining oscillator delivery?again! jito -2 today?nd tomorrow 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? or -40 to + 85? operating range both smd and thru-hole packaging available fox quality built-in total technical support from the industry 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?l post product information on our website; www .foxonline.com. check it, contact your local fox representative, or call dir ect, 888-get-2-fox.

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. call, fax or visit us on the web today. fox electronics 5570 enterprise parkway fort myers, fl 33905 tel: 888-get-2-fox fax: 941-693-1554 we?e on your frequency. www.foxonline.com o ther f ox f requency c ontrol p roducts jito -2 o rdering i nformation the jito -2 series represents just a portion of the broad spectrum of frequency control products and solutions available from fox, includ ing: use the part description guide below to order the jito -2 oscillator you need: if you need assistance in selecting the proper jito -2 oscillator for your specific application, fox s skilled technical support team will be glad to assist you. just call us. ** check availability of c and d stability with m temperature range supply voltage: 5 = + 5.0v 3 = + 3.3v stability: a = 100ppm b = 50ppm c = 30ppm** d = 25ppm** temperature range: e = -10? to + 70? f = -20? to + 70? m = -40? to + 85? package style: a = 14 pin dip b = 8 pin dip d = min-6 (5 x 7.5 x 1.5mm 6 pad smd) p = plastic (10x 13x 5mm) type: c = hcmos p = pecl s = hcmos (standby) jito -2 - b c 3 a m c ?106.250000 jito -2 p art d escription g uide frequency (mhz) c = custom (or leave blank) fx-3249-600-10m-fp revised june 2000 jito -t : (thru-hole, dual output pecl, tri-state) ask your customer service representative for details .
