What is clock？
In digital audio, the phase noise of the clock frequency can affect the jitter performance of DACs and degrade the quality of audio sources. To accurately reproduce high-resolution audio sources, the audio master clock signal is provided by an external quartz crystal oscillator with common frequencies including 11.2896MHz, 12.288MHz, 22.5792MHz, 24.576MHz, 45.1584MHz, 49.152MHz.
what is Crystal oscillator testing fixtures？
To ensure that the crystal oscillator meets the specifications of device manufacturers, crystal oscillator testing fixtures are widely used for testing and evaluating the performance parameters of crystal oscillators. These parameters include frequency stability, phase noise, temperature characteristics, etc., which are crucial for the performance and stability of digital audio devices.
Crystal oscillator testing fixtures can provide high-precision test results, helping users evaluate the performance of crystal oscillators under different operating conditions to ensure the clock system of digital audio devices is stable and reliable.
Moreover, in product applications, crystal oscillator testing fixtures can also be used for batch testing and screening of crystal oscillators to ensure consistent quality on the production line. By using crystal oscillator testing fixtures in the production process, production efficiency can be improved, non-conforming products can be reduced, and the performance and quality of the final products can meet standard requirements. The advantages of crystal oscillator testing fixtures include:
