Description:
Connor-Winfield's model VPLD34TEH
is a 3.3 Vdc, Voltage Controlled Crystal
Oscillator (VCXO) in a 9x14mm surface
mount package. The VPLD34TEH is
designed for use in SONET / SDH
systems requiring low litter and tight
frequency stability. No PLL multiplication
is used in the design of this VCXO.

Notes
1. Absolute Pull Range (APR) is the minimum guaranteed pull range of the VCXO under all conditions over lifetime operation
including calibration @ 25°C,frequency stability vs. the change in temperature, frequency vs. change in supply voltage,
frequency vs. change in load, shock and vibration and 10 years aging. The APR is referenced to (Fo).
2. When oscillator is disabled the true output is in a low state (Vol) and the complementary output is in the high state (VoH).
3. Output terminated into 50 ohms into Vcc – 2.0Vdc or Thevenin equivalent.
