Fox Contact Information  
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.

past the decimal point  
H = HCMOS  
L = LVDS

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  
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
