CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield
VPML63121 is a surface mount
3.3V Voltage Controlled Crystal
Oscillator (VCXO) with
Differential LVPECL outputs.
Based on a fundamental
crystal design, the VPML63121
is designed for phased lock
loop applications requiring low
jitter and tight stability.

Notes
1.0 Control Voltage @ 1.65V, relative to the frequency measured at 25°C.
2.0 Includes deviation over temperature, supply and load variations, shock, vibration and 15 years aging. Does not
include calibration.
3.0 Referenced to Fo at T=25°C Positive Slope.
4.0 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.
5.0 Output terminated into 50 ohms into Vcc – 2.0Vdc or Thevenin equivalent.
