XPRESSO utilizes a family of proprietary ASICs, designed and developed by Fox, with a key focus on noise reduction technologies. The 3rd order Delta Sigma Modulator reduces noise to the levels that are comparable to traditional Bulk Quartz and SAW oscillators. The ASICs family has ability to select the output type, input voltages, and temperature performance features. With the XPRESS lead-time, low cost, low noise, wide frequency range, excellent ambient performance, XpressO 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 part. XPRESSO 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 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 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 part. The Serial ID is unique for each and every XPRESSO part, and can be read by special Fox equipment. With the Serial ID, the below information can be obtained about that individual, XPRESSO part: • • • • • • • Equipment that the XPRESSO part was configured on Raw material used to configure the XPRESSO 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 part produced and can then obtain the information from above within 24 hours Page 9 of 15 © 2008 FOX ELECTRONICS | ISO9001:2000 Certified FXO-LC72 Series RoHS Material Declaration Material Name Cover Kovar Base Ceramic + Metallization + Nickel Plating + Gold Plating ＋Seal ring ＋silver solder ＩＣ ＩＣ Gold Adhesive Crystal Crystal Electrode Adhesive Component Nickel (Ni) Cobalt (Co) Iron (Fe) Alumina (Al2O3) Silicon Oxide (SiO2) Chromium Oxide (Cr2O3) Titanium Oxide (TiO2) Magnesium Oxide (MgO) Calcium Oxide (CaO) Tungsten (W) Molybdenum (Mo) Nickel (Ni) Cobalt (Co) Gold (Au) Iron (Fe) Nickel (Ni) Cobalt (Co) Silver (Ag) Copper (Cu) Aluminum (Al) Silicon (Si) Gold (Au) Silver (Ag) Epoxy Silicon Dioxide (SiO2) Silver (Ag) Nickel (Ni) Silver (Ag) Silicon (Si) TOTAL Content (mg) 5.09 3.15 9.47 79.178 3.143 3.379 0.873 0.437 0.297 12.272 0.380 4.740 0.395 0.624 5.809 3.119 1.829 2.269 0.400 0.0021 0.950 0.480 0.000210 0.0000700 2.04 0.019 0.000159 0.00037 0.000125 140.3 Page 10 of 15 © 2008 FOX ELECTRONICS | ISO9001:2000 Certified Content （ｗｔ％） 3.63% 2.24% 6.75% 56.4% 2.24% 2.41% 0.622% 0.311% 0.212% 8.74% 0.27% 3.38% 0.28% 0.445% 4.14% 2.22% 1.30% 1.62% 0.285% 0.00150% 0.68% 0.342% 0.000150% 0.0000499% 1.45% 0.0135% 0.000113% 0.000264% 0.000089% 100.00% (CAS Number) 7440-02-0 7440-48-4 7439-89-6 1344-28-1 14808-60-7 1308-38-9 13463-67-7 1309-48-4 1305-78-8 7440-33-7 7439-98-7 7440-02-0 7440-48-4 7440-57-5 7439-89-6 7440-02-0 7440-48-4 7440-22-4 7440-50-8 7429-90-5 7440-21-3 7440-57-5 7440-22-4 14808-60-7 7440-22-4 7440-02-0 7440-22-4 7440-21-3 FXO-LC72 Series 3rd Party (SGS) Material Report Page 11 of 15 © 2008 FOX ELECTRONICS | ISO9001:2000 Certified FXO-LC72 Series 3rd Party (SGS) Material Report (continued) Page 12 of 15 © 2008 FOX ELECTRONICS | ISO9001:2000 Certified FXO-LC72 Series Mechanical Testing Parameter Mechanical Shock Mechanical Vibration High Temperature Burn-in Hermetic Seal Test Method Drop from 75cm to hardwood surface – 3 times 10~55Hz, 1.5mm amplitude, 1 Minute Sweep 2 Hours each in 3 Directions (X, Y, Z) Under Power @ 125°C for 2000 Hours (results below) He pressure: 4 ±1 kgf / cm2 2 Hour soak 2,000 Hour Burn-In Burn-In Testing – under power 2000 Hours, 125°C Frequency Drift (PPM) XpressO LVDS Burn-In (Power on) Freq = 10MHz, N = 120 10 5 0 -5 -10 -15 -20 Initial 250 hours 500 hours 1000 hours Page 13 of 15 © 2008 FOX ELECTRONICS | ISO9001:2000 Certified 2000 hours FXO-LC72 Series MTTF / FITS Calculations Products are grouped together by process for MTTF calculations.
