Notes:
1. Inclusive of calibration @25C, frequency stability vs. temperature, control voltage
(Vc) = 1.65 Vdc and aging for ten years.
2. Referenced to Fo at T=25C 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. 50 ohm termination into Vcc-2V or Thevein equivalent.

The Connor-Winfield V301 is a 3.3V
Voltage Controlled Crystal Oscillator (VCXO)
with LVPECL Differential outputs. The V301 is
designed for use with PLL systems in SONET/
SDH systems requiring low jitter and tight stabil-
ity. No multiplication schemes are used in this
oscillator design.
