Description
The Fox XPRESSO Crystal Oscillator is abreakthrough in configurable Frequency ControlSolutions. XPRESSO utilizes a family of
proprietary ASICs, designed and developed byFox, with a key focus on noise reduction
technologies.
The 3rd order Delta Sigma Modulator reduces
noise to the levels that are comparable totraditional 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 choiceover the conventional technologies.

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 theLOT 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 andidentification.
If the parts become separated from the label showing the LOT Number, it can be retrieved from inside oneof the parts, and the information that can be obtained is listed below:•••••

Customer Purchase Order Number
Internal Fox Sales Order NumberDates 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. TheSerial 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:
