Radiation

Radiation testing is not performed, but these VCXOs have been acceptable for use in

environments up to 100K rads by analysis of the components used. They are

assembled with all bipolar semiconductors with the exception of the ACMOS chip

used for the CMOS output which is purchased from a wafer that has been tested to a

minimum of 100K rads total dose. A copy of the parts list and materials can be

provided for review.

These limits guarantee that under the worse case conditions of temperature, supply voltage, load stability

and 10 years aging, that the oscillator can be pulled back on to nominal frequency with the Control

MANUFACTURING INFORMATION

TRAVELLERS

Travellers or Process Cards are used in the manufacturing and testing of all of the 1794 Series VCXOs and

are available for customer review. Copies of these Travellers can be provided with the VCXOs at time of

shipment if so specified on the purchase order.

TRACEABILITY and HOMOGENEOUS MATERIAL

Option Codes S & R only

Manufacturing lot and date code information shall be recorded, by VCXO serial number, of every componen

t

and all materials used in the manufacture of that VCXO. Also all semiconductors used in the manufacture of

any given Production Lot of VCXOs, shall be from the wafer and have the same manufacturing lot date code.

A Production Lot, as defined by Corning, is all oscillators that have been kitted and assembled as a single

group. After the initial kitting and assembly, this Production Lot may be divided into multiple sublots to

facilitate alignment and test capacity and may be sealed at multiple times within

a 13 week window.

TEST DATA

All Test Data is recorded by VCXO serial number. Copies of this data can be provided with the VCXOs at time

of shipment if so specified on the purchase order.

REWORK

All rework follows the requirements of Mil-PRF-55310 Class S for Option Code S and Class B for Option

Codes R , B and C . The only exception is the Select-

At

-

Test components may be replaced up to four times.
