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, certified wafer lot can be provi-
ded if specified on the Purchase Order. A copy of the parts list and materials can be
provided for customer review.
MANUFACTURING INFORMATION
QUARTZ CRYSTAL
For the flight 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 ship-
ment 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 TCXO serial number, of every compo-
nent and all materials used in the manufacture of that TCXO. Also all semiconductors used in the manu-
facture of any given Production Lot of TCXOs, 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 assemb-
led as a single group. After the initial kitting and assembly, this Production Lot may be divided into multi-
ple 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 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.
