High Frequency
SMT 5.0x7.0mm
LVPECL VCXO
The Connor Winfield models V7
V7
are 3.3V, Surface Mount
5.0x7.0mm, Voltage Controlled
Crystal Oscillator (VCXO) with
LVPECL differential outputs and enable/
disable function. The
are
designed for use with applications utilizing a
PLL system requiring very high frequency
and low jitter. The surface mount package is
designed for high-density mounting and is
optimum for mass production.

Notes
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.
3.0
50 ohm termination into Vcc-2V or Thevein equivalent.
