Fox Contact Information

The 4^thorder Delta Sigma Modulator reduces noise to

the levels that are comparable to traditional Bulk

Quartz and SAW oscillators. The ASICs family has

the ability to select the output type and supply

voltage.

With the X^PRESSO-ULTRA lead-time, low cost, low

noise, wide frequency range, excellent ambient

performance, X^PRESSO-ULTRA is an excellent choice

over the conventional technologies.

Finished X^PRESSO-ULTRA 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 X^PRESSO-ULTRA part.

XPRESSO-ULTRA 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 X^PRESSO-ULTRA 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 X^PRESSO-ULTRA 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 X^PRESSO-ULTRA

part. The Serial ID is unique for each and every X^PRESSO-ULTRA part, and can be read by special Fox

equipment.

With the Serial ID, the below information can be obtained about that individual, X^PRESSO-ULTRA part:



Equipment that the X^PRESSO-ULTRA part was configured on

Raw material used to configure the XPRESSO-ULTRA 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 X^PRESSO-ULTRA part produced and can then obtain the information from above within 24

hours
