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
No connection or Logic ‘1’ to pin 1 enables oscillator
output
Maximum ‘pull-down’ resistance required to disable
output = 20kΩ

Model number -22, -22I = Non tri-state & -23, -23I = Tri-state
Operating Temperature Code: I = -40 to 85°C Not applicable for 0 to 70°C
Frequency Stability: A = ±25ppm, 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 practise the actual values are generally lower depending upon the spot frequency chosen. For typical values please
