–50 to 125°C
Logic ‘1’ (2.0Vmin) to pad 1 enables oscillator output,
Logic ‘0’ (0.8Vmax) 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
When oscillator is enabled, maximum transition time = 100ns

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.
For higher frequencies than shown above, please see our CFPP-57 Programmable Oscillator series.
