Working Principle

The SIT8208AI-G2-33S-38.400000T relies on a quartz crystal to generate a stable frequency, which is then used to drive a voltage-controlled oscillator (VCO) circuit. The VCO is a form of oscillator that generates an output signal with a frequency that is proportional to its applied voltage. The VCO’s output is then fed back to the quartz crystal, which serves as a resonator for the signal.

The frequency of the output signal is adjustable via a tuning voltage applied to the VCO’s input. This allows the device to be tuned to specific frequencies, including the 38.4MHz that is specified for this TCXO. This voltage is generated via a temperature sensor located on the device, which senses environmental temperature and adjusts the tuning voltage accordingly.

In addition to the temperature sensor, the SIT8208AI-G2-33S-38.400000T also contains circuitry to compensate for changes in the frequency over time. This allows the device to maintain a stable frequency output, even when exposed to changes in temperature and power supply voltage.

Conclusion

The SIT8208AI-G2-33S-38.400000T is a comprehensive electromechanical oscillator that is widely used in both cellular communications and wireless communication systems. Its high frequency accuracy, temperature-compensated design, and frequency stability make it an excellent choice for applications that require precision oscillator performance. Using a quartz crystal and a voltage-controlled oscillator, the SIT8208AI-G2-33S-38.400000T generates a signal with a frequency of up to 38.4MHz with excellent frequency stability and accuracy.
