500DSAB20M0000ACF

Oscillators are indispensable elements in modern electronic systems. The 500DSAB20M0000ACF oscillator is an example of a commonly used oscillator. It is used in a wide range of applications including radio broadcast, broadband access, microwave back haul, and cellular applications. The 500DSAB20M0000ACF oscillator has an extremely low phase noise of -70dBc/Hz at 10kHz offset. This low phase noise makes it ideal for use in systems requiring low jitter.

The 500DSAB20M0000ACF oscillator is based on a buck-boost converter exclusive to these types of oscillators. This converter consists of two MOSFET switches, a boost inductor, a buck capacitor and an interconnected control circuit. By switching the two MOSFETs in an alternating manner, energy stored in the boost inductor is alternately delivered to the output and the capacitor is charged. The stored energy in the boost inductor allows for continuous current flow even when the switch is open. This also prevents the output from shorting when the switch is opened.

The 500DSAB20M0000ACF oscillator has an asymmetric duty cycle of two thirds in the boost mode and one third in the buck mode. This duty cycle ensures that energy stored in the boost inductor is fully recovered in the buck mode, and thus the output current is maintained at the flow level. Additionally, the asymmetric duty cycle also reduces harmonic distortion and results in smoother waveforms.

The 500DSAB20M0000ACF oscillator also uses a phase-locked loop (PLL) circuit to achieve low jitter and high precision. In the PLL circuit, the output frequency is fed back and compared against an external reference signal. If there is any discrepancy between them, the input current of the oscillator is regulated until it reaches the same frequency as the reference signal. The 500DSAB20M0000ACF oscillator\'s PLL circuit is capable of achieving a frequency stability of 0.25 ppm/°C.

The 500DSAB20M0000ACF oscillator is a reliable and efficient oscillator used in a wide range of applications. It has low phase noise, a symmetrical duty cycle, and PLL circuit for high precision. Additionally, its flexibility to operate in various conditions makes it ideal for many different applications. Consequently, the 500DSAB20M0000ACF oscillator is one of the most widely used oscillators in modern electronic systems.
