CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield VPLB52TED is
a 3.3V Voltage Controlled Crystal
Oscillator (VCXO) with selectable
output frequency and LVPECL
Differential outputs. The VPLB52TED
is designed for use with PLL systems
in SDH/SONET systems requiring low
jitter and tight stability. No uses of
multiplication schemes are used in
this oscillator design.

PROCESS RECOMMENDATIONS
TABLE 6.0
Solder Reflow
The component solder used internal to this device has a m elting point of
221
°C. The peak temperature inside the device should be less than or equal
to 220
°C for a maximum of 10 seconds
Wash
Ultrasonic cleaning is not recommended.
Notes
1.0
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.
2.0
Absolute pull range (APR) is the minimum guaranteed pull range of the VCXO under all conditions over lifetime operation.
The APR is referenced to Fo.
3.0
50-ohm termination into Vcc-2V or Thevein equivalent.
