TCXO
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. They 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 provided if specified on the Purchase
Order. A copy of the parts list and materials can be provided for customer review.

MANUFACTURING INFORMATION
QUARTZ CRYSTAL
TCXO
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 of the 1623 Series TCXOs and
are available for customer review. Copies of these Travellers can be provided with the TCXOs 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 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 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 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.
