Description
The Fox XPRESSO Crystal Oscillator is a breakthrough in configurable Frequency Control Solutions. 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. Finished XPRESSO parts are 100% final tested.

Traceability - LOT Number & Serial Identification
LOT Number
The LOT Number has direct ties to the customer purchase order. 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
www..com 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
