3.3.2 Temperature Range
Operating range is −55 °C to +125 °C.
3.3.3 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.
3.3.4 Frequency Aging
Aging limits, and when tested in accordance with MIL-PRF-55310 Group B inspection, shall not
exceed ±1.5 ppm the rst 30 days, ±5 ppm Year 1 and ±2 ppm per year thereafter.
3.3.4.1 Frequency Aging Duraon Opon
For Screening Option S, the Aging test will be terminated after 15 days if the measured aging rate
is less than half of the specied aging rate. This is a common method of expediting 30-day Aging
without incurring risk to the hardware and used quite successfully for numerous customers. It is
based on the ‘least squares t’ determinations of MIL-PRF-55310 paragraph 4.8.35. The ‘half the
time/half the spec’ limit is generally conservative as roughly 2/3 of a unit’s Aging deviation occurs
within that period of time. Microchip’s automated aging systems take about 6 data points per day,
so a large amount of data is available to do very accurate projections, much more data than what
is required by MIL-PRF-55310. The delivered data includes the Aging plots projected to 30 days. If
the units do not perform within that limit, then they continue to the full 30-day term. For all other
screening options, please make a note on the purchase order if this is an acceptable option as it
assists in job planning and minimizes lead time.
3.3.5 Operang Characteriscs
Symmetrical square wave limits are dependent on the device frequency and are in accordance with
Table 6-2. Waveform measurement points and logic limits are in accordance with MIL-PRF-55310.
Start-up time is 10.0 msec. maximum.
3.3.6 Output Load
ACMOS (10 kΩ, 15 pF). Test load congurations are in accordance with MIL-PRF-55310.
