The Connor-Winfield RoHS Compliant V301 is a
3.3V Voltage Controlled Crystal Oscillator (VCXO)
with LVPECL Differential outputs. The V301
is RoHS compliant and designed for use with
PLL systems in SONET/SDH systems requir-
ing low jitter and tight stability. No multiplication
schemes are used in this oscillator design.
Total Frequency Tolerance ±±2 ppm
Temperature Range 2° to 72°C
Differential LVPECL Outputs
Tape and Reel Packaging
RoHS Compliant as of 1±/±225
