CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield VPLD61B is
a 3.3V Voltage Controlled Crystal
Oscillator (VCXO) with Differential
LVPECL outputs and
Enable/Disable function. The
VPLD61B is designed for use with
PLL systems in SONET/SDH
systems requiring low jitter and
tight stability. No multiplication
schemes are used in this oscillator
design.
