Notes:
(1) These test inspections deviate from the screening requirements for Class 2 oscillators listed in MIL-PRF-55310.
(2) The maximum operating and storage temperature of the EX-219 is +85°C. The EX-219 shall not be exposed to temperature higher than +85°C for
an indefinite period of time. However, the EX-219 can tolerate manufacturing process temperatures up to +100°C maximum for 168 hours total
accumulative time.
(3) The design and construction of the EX-219 can withstand up to 1000g’s constant acceleration.
Group A Inspection (included 100% w/ screening options S and B)
Group A Inspection is performed in accordance with Table V of MIL-PRF-55310
Subgroup 1: Electrical test
Subgroup 2: Visual and Mechanical inspection
Subgroup 3: Solderability
Group B Inspection (included 100% w/ screening options S and B)
Group B Inspection consists of frequency aging testing in accordance with MIL-PRF-55310 with the exception of using a
3
rd
order log fit for the 1
st
year aging projection (see app note #11 for detailed information)
Group C Inspection (optional, destruct specimens required)
Group C Inspection is optional and shall be requested on the customer’s purchase order. Group C Inspection can be
performed in accordance with either MIL-PRF-55310 or MIL-PRF-38534
Other Notes
1. Contact factory for improved stabilities or additional product options. Not all options and codes are available at all frequencies.
2. Unless stated otherwise, all values are valid after warm-up time and refer to typical conditions for supply voltage, frequency control
voltage, load and temperature (25°C).
3. Phase noise degrades with increasing output frequency.
4. Subject to technical modification.
5. Contact factory for availability.
