VX-724
Quad Frequency HPLL VCXO
VX-724
Descrip on
The VX-724 is a quad frequency voltage controlled crystal oscillator, VCXO, based upon Vectron’s HPLL high performance phase locked loop
frequency mul plier ASIC that combines key digital synthesis techniques with VI’s proven core analog technology blocks. A standard low
frequency crystal provides the reference to the frac onal-n synthesizer so that virtually any frequency between 10MHz and 1200 MHz can be
factory programmed allowing quick turn manufacturing. The VX-724 has a 2 bit hardware Frequency Select func on that provides one of four
condi ons: Frequency 1, Frequency 2, Frequency 3, or Frequency 4.
