2. Referenced to Fo at T=25°C Positive Slope.
3. Absolute pull range (APR) is the minimum guaranteed pull range of the VCXO under all
conditions over lifetime operation including aging for ten years. The APR is referenced to Fo.
4. When oscillator is disabled both output are in a high impedance state (Tri-State)
5. Vod measured with 10 ohm resistor betwen the true output and the complementary output.
