3.7.3 Passive Elements: Established Reliability (ER) QPL components, failure level R minimum shall
be used or element lot evaluation shall be as per MIL-PRF-55310, class S, or MIL-PRF-38534,
Appendix C, Class K as applicable.
3.7.4 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 3.7.5 herein.
3.7.5 For Output Frequency up to 70 MHz, 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 for
ionizing radiation of up to100 krads Xsis Electronics has also performed SET & SEL testing on the
microcircuit die. Test reports are available on request. For output frequencies above 100 MHz, the
microcircuit die shall be from 0.8 µm BiCMOS Si family and must be from wafer lots that have been
successfully tested in the oscillator for ionizing radiation of up to 100Krads and is known to be
2
Single Event Latch-up immune for LET of up to 95 Mev-cm /mg.
3.7.6 Workmanship, Rework and Process controls shall be in accordance with the requirements of
MIL-PRF-55310.
3.7.7 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 2.5 VDC for the following parameters:
Input Current
Output High Level
Output Low Level
10% change Maximum
10% change Maximum
0.1V change Maximum

Group A inspection shall be in accordance with MIL-PRF-55310 for product level S.
Group B inspection ( 30 day aging ) shall be in accordance with MIL-PRF-55310 for product level S.
In order to expedite delivery, by customer request, the aging test can be ended after 15 days if the
amount of frequency aging is less than 50% of the 30 day specification limit.
Oscillators 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. When specified by the
Customer, Xsis Electronics will perform Group C testing at an additional charge.
