1.0
Absolute pull range (APR) is the minimum guaranteed pull range of the VCXO under all
conditions over the lifetime operation. Including calibration @ 25°C, frequency vs.
change in temperature, frequency vs. change in supply voltage, frequency vs. change in
load, shock and vibration and aging for ten years. The APR is referenced to Fo. Positive
Transfer Function.
2.0
Outputs are enabled with no connection on pad 2. When oscillator is disabled both
outputs are in a high impedance state.
