Logic ‘1’ to pad 1 enables oscillator output, 2.0V min
Logic ‘0’ to pad 1 disables oscillator output; when
disabled the oscillator output goes to the high
impedance state, 0.8Vmax
No connection to pad 1 enables oscillator output
When oscillator is enabled, maximum transition time
= 100ns

Model number: 57, 57I = Tri-state 53, 53I = Non Tri-state
Operating Temperature Code: I = –40 to 85°C; Not applicable for 0 to 70°C
Frequency Stability: B = ±50ppm; C = ±100ppm
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 series.
