Programmable oscillators are electronic devices that generate a periodic signal. The signal can be generated with frequency, timing, or amplitude characteristics. These oscillators are designed to be used in various applications. SIT8208AC-8-25E is a programmable oscillator specifically developed for low voltage and lower power applications.

Application Field

SIT8208AC-8-25E is used for applications such as communication systems, signal processing systems, and data acquisition systems. It can also be used in low-power embedded systems, as well as industrial, automotive, and medical applications.

It is specially designed to reduce the power consumption and extends the battery life of the system. The device is suitable for portable, battery powered applications and can operate from a 2.7V to 3.6V power supply. Since it uses a low voltage supply it reduces its own power consumption.

The SIT8208AC can operate in a wide temperature range of -40°C to 85°C and is immune to ESD immunity up to 2kV. It is also resistant to surges and power interruptions, making it ideal for use in industrial and automotive environments.

Working Principle

SIT8208AC-8-25E is a two-wire programmable oscillator with an embedded controller and a low-power oscillator circuit. It works with a serial data bus that is used to program the oscillator frequency, as well as its other characteristics. The embedded controller processes the data bus commands and adjusts the oscillator frequency according to the command.

The on-chip low-power oscillator circuit generates the output signal. It is designed to be able to shift the oscillator frequency with minimal power consumption. The device can also operate in alternate modes such as burst mode, frequency-shift mode, and amplitude-shift mode, which can be programmed by the user.

The SIT8208AC-8-25E offers frequencies up to 25 MHz, with a typical stability of ±40ppm over temperatures from -40°C to 85°C. It has a synchronous start-up time of less than 20µs, which increases the system reliability and lowers the power consumption of the device.

Conclusion

SIT8208AC-8-25E is a low voltage, low power programmable oscillator designed for communication, signal processing, data acquisition, and embedded applications. It is suitable for portable and battery powered applications, and offers frequencies up to 25MHz and a typical stability of ±40ppm over temperatures from -40°C to 85°C. The device also has a synchronous start-up time of less than 20µs, which increases the system reliability and lowers the power consumption of the device.
