Introduction to Programmable Oscillators

Programmable oscillators are electronic oscillator circuits which generate an electrical oscillating signal with a fixed frequency set by a pre-programmed digital code stored in programmable non-volatile memory. They are widely used in applications such as frequency synthesisers, clock drivers and microprocessor timing circuits. The SIT3809AI-2-18NE is a programmable oscillator from the SIT3809 family of ICs from Silicon Technologies.

SIT3809AI-2-18NE Application Field

The SIT3809AI-2-18NE is an application-specific programmable oscillator, designed for use in a range of industrial and consumer applications. It is an ultra-low-power and highly accurate device, providing a wide range of programmable frequencies from 1.2MHz up to 18MHz. It is also capable of supporting both digital and analog signals, with adjustable duty cycles and rise/fall times. The main applications for this device include microprocessor timing, motor and motor synchronisation, frequency synthesisers, clock drivers, remote control and communications. Additionally, this oscillator is suitable for use in a variety of medical, industrial and consumer applications.

SIT3809AI-2-18NE Working Principle

The SIT3809AI-2-18NE works in a very similar way to other programmable oscillators, as it essentially uses a digitally programmable oscillator circuit to precisely determine the frequency and duty cycle of the output signal. The circuit is comprised of an integrated voltage controlled oscillator (VCO), a crystal oscillator, a highspeed programmable logic array (PLA), and a coordinate programmable oscillator circuit. The crystal oscillator sets the external clock signal frequency, and the PLA provides the control signals needed to accurately determine the frequency and duty cycle of the output signal. The VCO and PLA are both connected to the coordinate programmable oscillator circuit, and the output signal from the circuit is determined by the values selected in the programmable nonvolatile memory. The signal generated is a precise and stable sine wave signal, with a very low jitter and a wide dynamic range.

Conclusion

The SIT3809AI-2-18NE programmable oscillator can be used in a wide range of applications, and is capable of providing precise and stable sine wave signals with very low jitter and a wide dynamic range. It has a wide range of programmable frequencies from 1.2MHz up to 18MHz, and supports both analog and digital signals, with adjustable duty cycles and rise/fall times. Furthermore, it is an ultra-low-power and highly accurate device, making it a great choice for many industrial, consumer and medical applications.
