What is a VCXO ?
Logic: TTL / CMOS
Wave Form: Square
Crystal
MERCURY
Since 1973
Unlike regular clock oscillator which has fixed output frequency, the output
frequency of a
VCXO
(also known as “frequency
modulator”)
can be tuned
±50~±200 ppm up or down from the nominal frequency by varying the
control voltage on the voltage control pin. Varactor, a voltage variable
capacitance tuning diode, is used to achieve this purpose.

Varactor
Applications of VCXO include (PLL) phase lock loop, SONET/ATM, set-top
boxes, MPEG , audio-video modulations, video game consoles and HDTV sets.
