Glossary - alphabet order - "V"
This is the symbol for a transistor's collector pin (positive power supply pin) and for power supply voltage values. Although the symbol VDD is sometimes used instead, it has a different meaning in the strict sense. See "VDD".
Abbreviation for "Voltage Controlled SAW Oscillator". For further description, see "Voltage controlled SAW oscillator".

Abbreviation for "Voltage Controlled X'tal (crystal) Oscillator". For further description, see "Voltage controlled crystal oscillator".
Reference: Voltage controlled crystal oscillator
This is the symbol for a drain power supply pin for MOS type IC or power supply voltage value.
It is a method of forming a thin film on the surface of a substrate by evaporating and depositing metal or dielectric materials in vacuum. The method includes resistance heating vacuum evaporation, E.B. heating vacuum evaporation, sputtering, ion plating, and CVD (Chemical Vapor Deposition)
Voltage controlled SAW oscillator
This type of SAW oscillator (abbreviated as VCSO) includes a function that uses applied voltage to control the oscillation frequency. Generally, it is used for higher frequency bands of at least several hundred MHz. Seiko Epson markets voltage-controlled SAW oscillators in its EV Series.
Voltage controlled crystal oscillator
This type of crystal oscillator (abbreviated as VCXO) includes a function that uses applied voltage to control the oscillation frequency. Generally, it is used for automatic control systems that include various sensors for controlling the reception frequency. Usually, it also includes a variable capacitor for controlling the oscillation frequency. Seiko Epson markets voltage-controlled crystal oscillators in its VG series and TCO series.
