Working Principle

The MXO45HST-3C-39M7300 oscillator works by providing a stable output frequency. This is achieved via a Temperature Compensated Crystal Oscillator (TCXO) with an integrated reference voltage regulator and buffer amplifier. The TCXO utilizes a temperature-compensated quartz element to provide a stable frequency output across a wide range of temperatures. The reference voltage regulator is integrated into the die, and provides a stable power supply rail for the TCXO.

The integrated buffer amplifier converts the digital control voltage input into an analogue output frequency. The digital control voltage is then used to determine the frequency of the output signal. This allows for a wide range of frequency control options, including frequency synthesis, spread-spectrum frequency control, and direct digital synthesis. The oscillator can be programmed using standard I2C interface.

In addition, the MXO45HST-3C-39M7300 oscillator is designed to provide a high level of immunity to electromagnetic interference (EMI) and power supply noise. It also offers low settling time, low jitter, and high jitter tolerance, making it a suitable solution for a wide range of applications.

Conclusion

The MXO45HST-3C-39M7300 oscillator is a high-performance, fully-integrated solution for frequency control. It is suitable for use in applications up to 3900 MHz, and offers phase noise performance of -106 dBc/Hz at 1 kHz offset, and spectral purity of -103 dBc at 1 MHz spacing.
