Pin Configurable/Selectable Oscillators

The 512DAA000828AAGR is a pin configurable/selectable oscillator that provides accurate and reliable performance in a wide range of applications.

Application Field

The 512DAA000828AAGR oscillator is well-suited for a variety of applications, including those used to drive clocks in digital systems. Its small size and low pin-count make it an ideal choice for single-frequency designs requiring minimal board space.

It can also be used for precision timing and frequency synthesis in digital communication, instrumentation and test equipment systems.

The oscillator also provides low-power operation and excellent EMI tolerance, making it an ideal choice for automotive applications where power consumption and EMI performance are key considerations.

Working Principle

The 512DAA000828AAGR oscillator operates on a principle of digital-controlled analog circuitry. This allows the oscillator to be configured and programmed with a desired frequency and output polarity in a manner similar to a programmable logic device.

This circuitry includes a phase-locked loop (PLL) and a voltage-controlled oscillator (VCO). The PLL is used to feedback and phase-lock its output frequency to a precision reference frequency. It also provides selectable dividing ratios, allowing the output frequency to be programmed from a wide range.

The VCO is used to convert the feedback frequency of the PLL into a precision analog output signal. The frequency of this output signal is adjustable by varying the supply voltage and the temperature of the oscillator.

In addition, the 512DAA000828AAGR provides a selectable output phase polarity, which can be used to facilitate phase-locked loop (PLL) synchronization and other applications which require synchronized outputs.

Conclusion

The 512DAA000828AAGR is a pin configurable/selectable oscillator that is well suited for a variety of applications ranging from simple digital systems to sophisticated frequency synthesis and synchronization. It also provides low power operation and excellent EMI tolerance, making it an ideal choice for automotive applications.
