CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield V351 is
a 3.3V Voltage Controlled
Crystal Oscillator (VCXO)
with Differential LVPECL
outputs and Enable/Disable
function. The V351 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.
