Tri-state Operation
s
Logic ‘1’ to pad 1 enables oscillator output,
IQXO-70 2.2V min, IQXO-71 0.7Vs min
Logic ‘0’ to pad 1 disables oscillator output; when
disabled the oscillator output goes to the high
impedance state, IQXO-70 0.8V max, IQXO-71 0.3Vs
max
No connection to pad 1 enables oscillator output
