ATS15A

ATS15A Application Field and Working Principle

The ATS15A is part of the Frequency Tuned Voltage Controlled Crystal Oscillator (VCCXO) family and is a high-performance voltage-controlled crystal oscillator (VCXO) designed for use in frequency synthesizers, telecom and networking systems, instrumentation, and test equipment. The oscillator is factory programmed and can be adjusted over a range of frequency and voltage variations, making it versatile and ideal for applications requiring frequency control over wide temperature ranges.

The ATS15A is designed with a frequency range of between 20 and 100 MHz, depending on your application requirements. It has a wide tuning range (+/- 3MHz), fast settling time, low phase noise, and low EMI.In terms of applications, the ATS15A is suitable for frequency synthesisers, instrumentation, and test equipment, as it is capable of operating in a wide input voltage range. Furthermore, it is capable of operating at ambient temperatures from -40 to +85C and is compliant with the RoHS Directive standards.

Working Principle

The ATS15A uses a Voltage-Controlled Crystal Oscillator (VCCXO) to provide precise frequency control and stable operation over a wide voltage range. The oscillator operates by taking an input voltage and producing an output frequency. The output frequency is determined by the input voltage, which is adjusted by an external voltage reference. This voltage reference is then used to tune the frequency of the oscillator over its entire range.

The ATS15A also has a non-volatile memory (EEPROM) that is used to store tuned frequencies and their respective voltage settings. With this feature, the oscillator can be tuned over a wide range of frequencies without needing to be re-programmed each time.

Conclusion

In conclusion, the ATS15A is a highly versatile and reliable precision crystal oscillator suitable for use in frequency synthesizers, instrumentation, and test equipment. Its wide tuning range, fast settling time, low phase noise, low EMI, and wide temperature range make it perfect for a variety of applications. With its innovative voltage-control and non-volatile memory, it can be easily tuned over a wide range of frequencies without needing to be re-programmed each time.
