Working Principle

The SIT1602AI-11-18E-72.000000E utilizes a temperature compensated crystal oscillator (TCXO) to achieve frequency accuracy and stability over a wide temperature range. This consists of a quartz crystal connected to the crystal oscillator circuit through feedback paths. A combination of PLL (Phase Locked Loop) and a capacitor-based control is used to produce a precise stable output frequency over a wide temperature range.

The quartz crystal vibrates at its resonant frequency as an LC circuit. The crystal oscillator circuit monitors the output frequency and adjusts the capacitance of the quartz crystal to maintain the oscillation frequency. The feedback network uses the output frequency difference between the crystal oscillator and the external clock. The oscillator can then match the voltage-temperature coefficients and track the oscillation frequency.

Conclusion

The SIT1602AI-11-18E-72.000000E TCXO is a suitable choice for applications requiring precise frequency stability over a wide temperature range. Its low power consumption, fast frequency support, and low-noise surface-mount package makes it an ideal device for a variety of electronic applications.
