VX-722
Dual Frequency HPLL VCXO
VX-722
Description
Features
Applications
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.
Features
Applications
PLL circuits for clock smoothing and frequency translation
