Marking: As a minimum, the parts shall be marked with Xsis P/N, Xsis cage code, ESD symbol,
date code and serial number.

Electrical Characteristics: See Table I
3.6.1 Total Dose Radiation: Hybrid Microcircuit Crystal Oscillators shall be capable of meeting the
electrical characteristics of Para. 3.6 after being exposed to total ionizing dose radiation of
100 krads as per MIL-STD-883, method 1019.
3.7
Hybrid Elements:
3.7.1 Quartz Crystals: High grade cultured quartz crystals shall be used. As an option, Xsis will use
premium Q swept quartz crystals at an additional charge. Crystal element evaluation shall be in
accordance with MIL-PRF-55310.

3.7.3 Microcircuit die shall be from lots that have passed the element evaluation per MIL-PRF-55310,
Appendix B, Level S, except testing per Subgroup 5 is omitted. Subgroup 5 testing is circuit
configuration dependent, therefore, it is more effectively performed at the oscillator level as
explained in Paragraph 3.7.4 herein.
3.7.4 Microcircuit die used in the oscillator shall be from NSC/FC 54ACT family and must be from
wafer lot that has been successfully tested in the oscillator proposed herein for ionizing radiation
of up to 100 krads.
3.7.5 Lot Traceability: Production lot for these oscillators shall be homogenous. Each element used in
the production lot shall be traceable to a single lot. Swept quartz shall be traceable to the quartz
bar, and its applicable processing details.
4.
Quality Assurance Provisions: The quality assurance provisions shall be per MIL-PRF-55310,
except as specified herein.
100% Screening: The 100% screening shall be performed as per Table II. PDA requirements for
nondestructive bond pull and burn-in shall be as specified below.
PDA for Nondestruct Bond Pull: Unless otherwise specified, PDA shall be 2% of total number of
wires or 1 wire whichever is greater.
PDA for Burn-in: Unless otherwise specified, PDA for burn-in shall be 2% or 1 oscillator whichever
o
o
is greater and shall be applicable to +23 C and/or +25 C static tests only. In addition Delta
Calculation shall be performed after Burn-in and shall count for PDA. All measured values for
Delta Calculation shall be recorded. Parts that exceed the specified delta limits shall be rejected and
be counted for PDA. Delta Calculation shall be performed at 5.0 VDC for the following parameters:
Input Current

Group B inspection shall be in accordance with MIL-PRF-55310 for product level S.
Parts shall be capable of meeting group C inspection per MIL-PRF-55310. Generic group C
inspection data on similar parts may be used to satisfy this requirement.
Inspection and Test Data: Unless otherwise specified in the purchase order, the following
Inspection and test data documentation shall be supplied with the parts.

replace letter “S” in the part number with letter “E”. Engineering Models use the
same design and elements as Flight Models except are subjected to MIL-PRF-55310 class B screening.
For
Prototype Model,
replace letter “S” in the part number with letter “P”. Prototypes are form, fit and
function equivalent of Flight Models. Prototypes may use class B elements.
