A Voltage-Controlled Crystal Oscillator (VCXO) has a voltage input that tunes its output frequency over a specified pulling range. It is primarily used in phase-locked loops (PLLs) for clock generation, frequency synthesis, jitter attenuation and clock recovery in communications systems.
Ultra-Low Phase Noise VCXO family has been designed specifically for High Definition Audio (HD Audio). It features a typical low close-in phase noise of -90 dBc/Hz @ 10 Hz offset, and a noise floor of -168 dBc/Hz. With this extreme low phase noise performance, you will "Hear the Difference". It also features a Standby Function - when placed in disable mode, the internal oscillator is completely shut down in addition to its output buffer being placed in Tri-State. This family is housed in a 9×14 mm SMT package and operates with a +3.3V power supply. Applications include: 1) Digital Audio Broadcasting (DAB) 2) Professional CD audio equipment 3) DACs and ADCs for HD audio
