Radiation
Radiation testing is not performed at the oscillator level, but these TCXOs have
been acceptable for use in environments of up to 100K rads total dose, by analysis
of the components used. The TTL Output TCXOs are assembled with all bipolar
semiconductors. The CMOS Output TCXOs are assembled with all bipolar
semiconductors with the exception of the ACMOS chip used to provide the CMOS
output. A CMOS chip that is from a radation tested, certi ed wafer lot can be provided
if speci ed on the Purchase Order. A copy of the parts list and materials can be
provided for customer review.

Manufacturing Information
QUARTZ CRYSTAL
For the ight models, swept quartz shall be used in the manufacture of the crystals. For the Engineering models, non-swept quartz
shall be used.
TRAVELLERS
Travellers or Process Cards are used in the manufacturing and testing of all Hi-Rel TCXOs and are available for customer review. Copies
of these Travellers can be provided with the TCXOs at time of shipment if so speci ed on the purchase order.
TRACEABILITY and HOMOGENEOUS MATERIAL
Option Codes ‘S’ & ‘R’ only
Manufacturing lot and date code information shall be recorded, by TCXO serial number, of every component and all materials used in
the manufacture of that TCXO. Also all semiconductors used in the manufacture of any given Production Lot of TCXOs, shall be from
the wafer and have the same manufacturing lot date code. A Production Lot, as de ned 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 TCXO serial number. Copies of this data can be provided with the TCXOs at time of shipment if so speci ed
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.
