Description
The VX-722 is a dual frequency voltage controlled crystal oscillator, VCXO, based upon Vectron’s HPLL high performance phase locked loop frequency multiplier 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 fractional-n synthesizer so that virtually any frequency between 10MHz and 1200 MHz can be factory programmed allowing quick turn manufacturing.
