4.1.3.1 Class B Microcircuits. When specified, microcircuits assembled into OS-68338 Design
Pedigree letters “B” and “C” devices (¶ 5.2a) are procured from wafer lots that have passed
MIL-PRF-55310 element evaluations for Class B devices.
4.1.4
Packages. Packages are procured that meet the construction, lead materials and finishes as
specified in MIL-PRF-55310. Package lots are upscreened in accordance with the
requirements of MIL-PRF-38534 as applicable.
4.1.5
Traceability. Class S active device lots are homogenous and traceable to the manufacturer’s
individual wafer. Swept Quartz Crystals are traceable to the quartz bar and the processing
details of the autoclave lot, as applicable. All other elements and materials are traceable to
their manufacturer and incoming inspection lots.
4.1.6
Enhanced Element Evaluation. When Design Pedigree Option “E” is specified, active and
passive devices with Enhanced Element Evaluation as listed in Table 6 and 7 shall be
implemented for the highest reliability preference.
4.2
Mechanical.
4.2.1
Package Outline. Table 1 links each Hi-Rel Standard Model Number of this specification to a
corresponding package style. Mechanical Outline information of each package style is found
in the referenced Figure.
4.2.2
Thermal Characteristics. The worst case thermal characteristics of each package style are
found in Table 4.
4.3
Electrical.
4.3.1
Input Power. Devices are designed for standard 5.0 volt dc operation, ±10%. Optional 3.3
Vdc (±10%) input performance for ACMOS output conditions. Current is measured, no load,
at maximum rated operating voltage.
4.3.2
Temperature Range. Operating range is -55°C to +125°C.
4.3.3
Frequency Tolerance. Initial accuracy at +23°C is ±15 ppm maximum. Frequency-
Temperature Stability is ±50 ppm maximum from +23°C reference. Frequency-Voltage
Tolerance is ±4 ppm maximum.
4.3.4
Frequency Aging. Aging limits, and when tested in accordance with MIL-PRF-55310 Group B
inspection, shall not exceed ±1 ppm the first 30 days, ±5 ppm Year 1 and ±2 ppm per year
thereafter. When screening Option F is selected, aging is performed on 100% of the lot and
Vectron does not apply the PDA as specified in MIL-PRF-55310. Data will be presented for
each individual unit to show compliance to the aging limit.
