Programmable Oscillators

SIT8009AI-71-XXX-000.FP000 is a programmable oscillator and is an important component used in electronics and technology applications that require precision periodic signals for synchronization. It combines the advantages of both quartz crystal tuning and microprocessor integrated look-up table (memory) to provide an adjustable frequency signal source with a wide frequency range.

Applications

Programmable oscillators are used in many different kinds of equipment and applications such as watches, GPS receivers and clocks, communications systems, radar systems, instrumentation and test and measurement, computer systems, and automobile engine control systems. These are used because they provide increased accuracy and flexibility. Programmable oscillators can be programmed to generate any desired frequency in the 14-500kHz range and also be programmed to generate signals with any duty cycle as long as the frequency is not too low. This makes them ideal for a wide range of applications.

Working Principle

The SIT8009AI-71-XXX-000.FP000 programmable oscillator employs a digital tuning scheme, called OMRON ZL-530K, which is based on a look-up table containing individual frequencies for every combination of input codes.It has a 16-bit digital tuning mechanism which allows for more precise tuning and more frequencies to be stored in the memory. It also contains a voltage-controlled oscillator (VCO), which is used to generate the actual oscillation signal. The VCO is connected to a variable resistor, which allows the frequency to be adjusted by changing the resistance across the VCO.

The SIT8009AI-71-XXX-000.FP000 programmable oscillator also includes a main control unit, which acts as a microprocessor and is responsible for setting the oscillation frequency. This is done by reading the frequency codes stored in the look-up table and providing the appropriate signal level to the VCO. Additionally, the control unit also controls the configuration and operation of the oscillator, as well as programming and storing the frequencies.

Conclusion

The SIT8009AI-71-XXX-000.FP000 programmable oscillator is an excellent choice for any application that requires a precise, adjustable frequency signal source with a wide range of frequency capabilities. It employs a high-precision digital tuning system and a voltage-controlled oscillator to provide the most accurate and reliable signal available. It is an important component in many electronic and technology applications.
