Meaning of CRYSTAL OSCILLATOR (XO) in English

CRYSTAL OSCILLATOR (XO)

An oscillator in which the frequency is controlled by a piezoelectric crystal. Note 1: A crystal oscillator may require controlled temperature because its operating frequency is a function of temperature. Note 2: Types of crystal oscillators include voltage-controlled crystal oscillators (VCXO), temperature-compensated crystal oscillators (TCXO), oven-controlled crystal oscillators (OCXO), temperature-compensated-voltage controlled crystal oscillators (TCVCXO), oven-controlled voltage-controlled crystal oscillators (OCVCXO), microcomputer -compensated crystal oscillators (MCXO), and rubidium crystal oscillators (RbXO).
