Oscillators

VCXO - Bliley Technologies, Inc. (Bliley)

A VCXO Voltage-Controlled Crystal Oscillator is a crystal oscillator that''s frequency can be adjusted by an externally applied voltage. VCXO''s have a wide variety of applications in frequency modulation (FM) and phase-locked-loop (PLL) systems. Typical deviation ranges can be 10 ppm to as much as 2000 ppm. The device that allows a crystal oscillator''s frequency to be voltage controlled is known as a varactor diode.
