Phase-Locked Voltage Controlled Oscillator

Model PLVCO

Features

Output frequencies from 10 MHz to 32 GHz
Low phase noise & spurious
Harmonics (typ.) -30 dBc
Internal (±0.5PPM) or external reference frequency
Low power +5.5V operation
Small size (2.25″ x 2.25″ x 0.62″)
Lowest cost X-Band PLO

Description

The model PLVCO is a single PLL design that locks a voltage controlled oscillator (VCO) to either an external or internal reference. Due to the availability of VCO’s at a low cost this is a very simple way to realize a desired frequency. The performance is suitable for many applications and is the lowest cost PLO architecture we have available.
