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.

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 component 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.
