Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The SL2309SI-1H is a high-performance silicon oscillator that utilizes a patented circuit to achieve a high frequency-stability oscillator with a standard quartz crystal. This oscillator meets low-phase-noise requirements commonly found in wireless communication and test and measurement applications. It provides a low-cost alternative to temperature-compensated and voltage-controlled crystal oscillators, allowing customers to be competitive in the marketplace.

Application Field

The SL2309SI-1H is well suited for a wide range of applications, including among others:

• Wireless Infrastructure
• Test and measurement
• GPS, timing, and navigation systems
• Computer systems
• Consumer electronics
• In-car infotainment systems

Working Principle

The SL2309SI-1H silicon oscillator works by taking the signal from the quartz crystal and amplifying it with a differential amplifier stage. This signal is then filtered, through the use of an LC filter or active filter stage, resulting in a clean and low-distortion signal. The signal is then buffered using a voltage-controlled amplifier, with the gain being controlled by an external voltage source, such as a temperature sensor. This allows the oscillator to maintain a high frequency-stability tolerance regardless of the external temperature.

Benefits

The SL2309SI-1H silicon oscillator offers a number of advantages over its traditional quartz crystal counterparts:

• Low-phase noise, leading to improved signal integrity
• High frequency-stability, allowing the oscillator to maintain specified performance over a wide temperature range
• Low-cost, making it attractive for cost-sensitive applications
• Compact form factor, allowing for it to be incorporated into space-constrained designs

Conclusion

The SL2309SI-1H is an ideal solution for a wide range of applications. It offers the advantages of a traditional quartz crystal oscillator, with the added benefits of low noise, high frequency-stability, and low-cost. Its compact form factor allows for it to be incorporated into space-constrained designs with ease, making it a great choice for those looking for a reliable and cost-effective oscillator solution.
