Single Frequency HPLL VCXO
VX-721
Features
Description
Applications
The VX-721 is a voltage controlled crystal oscillator, VCXO, based upon Vectronâs HPLL high performance phase locked loop frequency
multiplier ASIC that combines key digital synthesis techniques with VIâs 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.
