(over operating temperature range)
Operating Temperature Ranges
■
0 to 70°C (IQXO-149)
■
–40 to 85°C (IQXO-149I)
Storage Temperature Range
■
–55 to 125°C
Environmental Specification
■
Terminal Strength: 0.91kg max. Force perpendicular to
top & bottom
■
Hermetic Seal: not to exceed 1
x10-8 mBar litres of
Helium leakage
■
Solderability: MIL-STD-202E, Method 208C
■
Vibration: 10 to 55Hz 0.76mm displacement, sweep 60
seconds, duration 2 hours
■
Rapid Change of Temperature over Operating
Temperature Range: 10 cycles
■
Shock: 981m/s2 for 6ms, three shocks in each direction
along the three mutually perpendicular planes
Tri-state Operation
■
Logic ‘0’ to pin 1 disables oscillator output; when
disabled the oscillator output goes to the high
impedance state
■
No connection or Logic ‘1’ to pin enables oscillator
output
■
Maximum ‘pull-down’ resistance required to disable
output = 20k
■
Disable current 50A typical
