The 7Q-16.368MBS-Toscillator uses a piezoelectric quartz crystal that produces mechanical vibration on application of voltage. This mechanical vibrationisconvertedintoelectricalenergyusingTransconductanceAmplifier (TCA). The transconduction coefficient of the TCA is chosen in such a way that the output frequency of the oscillator is stable.Thepropertiesofthecrystalprovideanoise suppressionmechanism which helps improve phase noise performance at higher frequencies. The TCA provides gain as well as linearity for the conversion from mechanical to electrical energy, while the oscillator is tuned through an external resistor connected to the crystal. The external resistor is adjusted properly to obtainspecifictuningfor the frequency.
