DescripƟon
Features
ApplicaƟons
The VX-724 is a quad frequency voltage controlled crystal oscillator, VCXO, based upon Vectron’s HPLL high performance phase locked loop
frequency mulƟplier 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 fracƟonal-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 funcƟon that provides one of four
condiƟons: Frequency 1, Frequency 2, Frequency 3, or Frequency 4.
