(over operating temperature range)
Operating Temperature Ranges
I
0 to 70°C (IQXO-22, -23)
I
–40 to 85°C (IQXO-22I, -23I)
Storage Temperature Range
I
–55 to 125°C
Environmental Specification
I
Terminal Strength: 0.91kg max. Force perpendicular to
top & bottom
I
Hermetic Seal: not to exceed 1x10-8 mBar litres of
Helium leakage
I
Solderability: MIL-STD-202E, Method 208C
I
Vibration: 10 to 55Hz 0.76mm displacement, sweep 60
seconds, duration 2 hours
I
Rapid Change of Temperature over Operating
Temperature Range: 10 cycles
I
Shock: 981m/s2 for 6ms, three shocks in each direction
along the three mutually perpendicular planes
Tri-state Operation (IQXO-23, -23I)
I
Logic ‘0’ to pin 1 disables oscillator output; when
disabled the oscillator output goes to the high
impedance state
I
No connection or Logic ‘1’ to pin 1 enables oscillator
output
I
Maximum ‘pull-down’ resistance required to disable
output = 20k
