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.
*Tighter stabilities may be available. Contact Fox Technical Support for details.

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
