Programmable Oscillators

Programmable oscillators are components whose frequencies are set or programmed as part of an overall design by the user. The frequencies can be programmed with a resistors, capacitors, varactors or even non-volatile memories. The SIT8008BCB3-28E is one such device, a low-power programmable oscillator which is widely used in consumer and industrial circuitry. The SIT8008BCB3-28E can be programmed to generate high quality clock signals at a wide range of frequencies from 13.2 KHz to 100 MHz.

Application Field

The SIT8008BCB3-28E is used for a variety of purposes, many of which are in consumer electronics. Examples of application fields include:

• Digital televisions, digital video disks, personal video recorders and set-top boxes
• Wireless modems
• Portable audio/video players
• Cordless phones and other wireless communication terminals
• Pagers and other personal radio equipment
• Computer accessories, including laptop and desktop systems

The SIT8008BCB3-28E is also used in database and network servers and other industrial equipment.

Working Principle

The SIT8008BCB3-28E includes two programmable components – a frequency setting resistor and a non-static 2-to-1 multiplexer – which allow it to be set to a specific frequency by the user. The frequency is determined by the ratio of the resistor to the capacitance of the multiplexer. The device also features a voltage-controlled temperature compensation (VCTC) circuit which helps to maintain consistent performance over a broad temperature range. This makes the SIT8008BCB3-28E suitable for use in a wide variety of environments. The SIT8008BCB3-28E is also X-ray and radiation tolerant, making it suitable for use in high-altitude aircraft, space missions and other applications in which it may be exposed to radiation. In addition, the device includes a power-on reset (POR) circuit, which resets the device automatically when the power is turned on. This ensures smooth operation when the device is turned on, even if power has been absent for some time.

Conclusion

The SIT8008BCB3-28E is a low-power programmable oscillator which is widely used in consumer and industrial applications. Its frequency can be set or programmed with a resistor, capacitors, varactors or even non-volatile memories. Additionally, the device features a voltage-controlled temperature compensation circuit and a power-on reset circuit, making it suitable for a wide variety of environment.
