Tri-state HCMOS (3.3V) (IQXO-71), Load 15pF max
±25ppm, ±50ppm, ±100ppm (inclusive of supply voltage and
output load variations over the operating temperature range)
–10 to 70°C (IQXO-70, -71)
–40 to 85°C (IQXO-70I, -71I)
–55 to 125°C
Logic ‘1’ (IQXO-70 2.2V min, IQXO-71 0.7Vs min) to pad 1
enables oscillator output
Logic ‘0’ (IQXO-70 0.8V max, IQXO-71 0.3Vs max) to pad 1
disables oscillator output; when disabled the oscillator output
goes to the high impedance state,
No connection to pad 1 enables oscillator output
Shock: MIL-STD-202F, Method 213B (1000G, 0.5ms, 1/2
sine)
Vibration: MIL-STD-202F, Method 204D, Test condition D

Operating Temperature Code: I = –40 to 85°C; Not applicable over –10 to 70°C
Frequency Stability: A = ±25ppm; B = ±50ppm; C = ±100ppm
*Note - Code IA, ±25ppm over –40 to 85°C is not available
Please note that the rise and fall times listed are the maximum values we specify to cover various frequency breaks. In practice the actual values are generally
lower depending upon the spot frequency chosen. For typical values please contact our sales office.
