Working Principle

The SIT1602BCA7-30E is based on a Temperature-Compensated Crystal Oscillator (TCXO) technology. The oscillator module consists of a temperature-compensated quartz crystal resonator, and a CMOS oscillator IC. The crystal resonator operates in an open-loop configuration, whereby the oscillation frequency is determined by the resonance of the quartz crystal and the control voltage.

The oscillator IC includes the necessary circuit elements to provide bias, amplifier and frequency control. The oscillator output is a square wave signal and can be DC-coupled directly to system electronics, and is suitable for a wide range of applications. The frequency accuracy is maintained by compensating for the variation in the resonance frequency of quartz crystal due to temperature fluctuation.
