CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield
VPLD34TEH is a 3.3V
Voltage Controlled Crystal
Oscillator (VCXO) with
Differential LVPECL outputs
and Enable/Disable function.
The VPLD34TEH is designed
for use with PLL systems in
SONET/SDH systems
requiring low jitter and tight
stability. No multiplication
schemes are used in this

Notes
1.0
Vcc = 3.3Vdc, Vc = 1.65V
2.0
Inclusive of calibration @ 25°C, frequency stability vs. temperature, supply and load variations, shock, vibration and
aging for ten years. Control voltage (Vc) = 1.65 Vdc.
3.0
Control voltage for (Fo) = 1.65 Vdc Typical. Positive Transfer Function.
4.0
When oscillator is disabled the true output is in a low state (Vol) and the complementary output is in the high state
(VoH)
5.0
50 ohm termination into Vcc-2V or Thevein equivalent.
