Output
The Connor-Winfield VPLC54TE is
a 3.3V voltage controlled crystal
oscillator (VCXO) designed for use
in phase locked loops of SONET /
SDH systems. Using no PLL multi-
plication schemes, the VPLC54TE
provides one pair of stable, low
jitter, LVPECL differential outputs.
Features:
3.3V Operation
Low Jitter <1ps RMS
Overall Stability ±20ppm
