Note:
N/A
(1) These test inspections deviate from screening requirements for class 2 oscillator in MIL-PRF-55310.
(2) The maximum operating and storage temperature of the EX-245 is +85°C. The EX-245 shall not be exposed to temperature higher than
+85°C at length of time.
(3) The design and construction of the EX-245 can withstand up to 1000g’s constant acceleration

Contact factory for improved stabilities or additional product options. Not all options and codes are
available at all frequencies.
Unless otherwise stated all values are valid after warm-up time and refer to typical conditions for supply
voltage, frequency control voltage, load, temperature (25°C)
Phase noise degrades with increasing output frequency.
Subject to technical modification.
