LVPECL VCXO
Model VL734
Description:
Features:
3.3V Operation
The Connor-Winfield VL734 is a 5x7mm,
3.3 Vdc LVPECL, Surface Mount, Voltage
Controlled Crystal Oscillator (VCXO)
designed for phase lock loop applications
requiring low jitter and tight frequency
stability. The VL734 uses multiplication to
achieve the final output frequencies. The
RoHS compliant surface mount package is
designed for high-density mounting and is
optimum for mass production.
Absolute Pull Range: 100 ppm
Temperature Range: 0 to 85°C
Tri-State Enable/Disable Pad 2
Low Jitter: <1ps RMS
