XPRESSO-ULTRA utilizes a family of proprietary ASICs, designed and developed by Fox, with a key focus on noise reduction technologies. The 4th 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 XPRESSO-ULTRA lead-time, low cost, low noise, wide frequency range, excellent ambient performance, XPRESSO-ULTRA is an excellent choice over the conventional technologies.

The LOT Number is marked on the “Reel” label, and also stored internally on non-volatile memory inside the XPRESSO-ULTRA part. XPRESSO-ULTRA parts that are shipped Tape and Reel, are also placed in an Electro Static Discharge (ESD) bag and will have the LOT Number labeled on the exterior of the ESD bag. It is recommended that the XPRESSO-ULTRA parts remain in this ESD bag during storage for protection and identification. If the parts become separated from the label showing the LOT Number, it can be retrieved from inside one of the parts, and the information that can be obtained is listed below: Customer Purchase Order Number Internal Fox Sales Order Number Dates that the XPRESSO-ULTRA part was shipped from the factory The assigned customer part number The specification that the part was designed for Serial Identification The Serial ID is the individualized information about the configuration of that particular XPRESSO-ULTRA part. The Serial ID is unique for each and every XPRESSO-ULTRA part, and can be read by special Fox equipment. With the Serial ID, the below information can be obtained about that individual, XPRESSO-ULTRA part: Equipment that the XPRESSO-ULTRA part was configured on Raw material used to configure the XPRESSO-ULTRA part Traceability of the raw material back to the foundries manufacturing lot Date and Time that the part was configured Any optimized electrical parameters based on customer specifications Electrical testing of the actual completed part Human resource that was monitoring the configuration of the part Fox has equipment placed at key Fox locations World Wide to read the Lot Identification and Serial Number of any XPRESSO-ULTRA part produced and can then obtain the information from above within 24 hours Page 9 of 11 © 2014 FOX ELECTRONICS | ISO9001:2008 Certified An Integrated Device Technology, Inc. company PRELIMINARY SPECIFICATIONS FXU-PC52 Series Mechanical Testing Parameter Test Method MIL-STD-202 Method 213 Condition C Mechanical Shock MIL-STD-202 Method 204 5g's for 20 minutes 12 cycles of each 3 orientations: X, Y, Z Mechanical Vibration Under Power @ 125°C for 1000 Hours High Temperature Operating Life (HTOL) Hermetic Seal He pressure: 4 ±1 kgf / cm2 2 Hour soak Page 10 of 11 © 2014 FOX ELECTRONICS | ISO9001:2008 Certified An Integrated Device Technology, Inc. company PRELIMINARY SPECIFICATIONS FXU-PC52 Series XpressO-ULTRA Home XpressO-ULTRA XOs XpressO Brochure Patent Numbers: US 6,664,860, US 5,960,403, US 5,952,890; US 5,960,405; US 6,188,290; Foreign Patents: R.S.A. 98/0866, R.O.C. 120851; Singapore 67081, 67082; EP 0958652 China ZL 98802217.6, Malaysia MY-118540-A, Philippines 1-1998-000245, Hong Kong #HK1026079, Mexico #232179 US and Foreign Patents Pending XpressO® Fox Electronics Contact Information (USA)-Worldwide Headquarters Tel: 888-GET-2-FOX Outside US: +1.239.693.0099, Fax:+1.239.693.1554 Email: www.foxonline.com/email.htm Fox EMEA Tel: +44.1283.568153 Email: www.foxonline.com/email.htm Fox Japan Tel:+81.3.3374.2079, Fax: +81.3.3377.5221 Email: www.foxonline.com/email.htm Fox Singapore Tel:+886-2-22073427, Email: www.foxonline.com/email.htm The above specifications, having been carefully prepared and checked, is believed to be accurate at the time of publication; however, no responsibility is assumed by Fox Electronics for inaccuracies.
