Oscillator
VPLD54TEM
VCXO
The Connor-Winfield VPLD54TEM is a 3.3V
Voltage Controlled Crystal Oscillator (VCXO)
with Differential LVPECL outputs and Enable/
Disable function. The VPLD54TEM is designed
for use with PLL systems in SONET/SDH sys-
tems requiring low jitter and tight stability. No
uses of multiplication schemes are used in this
oscillator design.

Notes:
1. 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.
2. Control voltage for (Fo) = 1.65 Vdc Typical. Positive Transfer Function
3. When oscillator is disabled the true output is in a low state (Vol) and the
complementary output is in the high state (VoH)
4. 50 ohm termination into Vcc-2V or Thevein equivalent.
