SL23EP08SC-3T Application Field and Working Principle

The SL23EP08SC-3T clock generator is a Single-Ended Programmable Spread-Spectrum Clock Generator (SSCG). It is designed to minimize output jitter and improve electromagnetic compatibility (EMC) performance. This device is characterized as small size, low noise, and excellent jitter performance, and is suitable for various communications and multimedia applications, including Bluetooth, Ethernet, DSL, digital video, and HD video. It is also suitable for both general purpose and microprocessor applications where clock signal accuracy is important.

It utilizes a single-ended spread-spectrum integrated circuit (SSIC), which is functionally divided into two sections. The first section contains the frequency synthesis logic for generating a spread-spectrum clock, which then feeds into the second section containing the logic for post-processing of the output clock signals. This spread-spectrum clock generator can generate frequencies from 0.1 MHz up to 200 MHz with excellent jitter performance.

Architecture and Features

The SL23EP08SC-3T clock generator supports input frequencies of up to 200 MHz and is based on a pre-tuned silicon-based spread-spectrum clock generator, providing excellent jitter performance. It can also dynamically adjust the spreading rate and jitter levels to varying input and output frequencies. The SL23EP08SC-3T also supports programmable spread-spectrum clock rates and jitter levels, allowing users to optimize system EMC performance without compromising performance.

The SL23EP08SC-3T clock generator is designed to be used in various applications including networking, digital video and broadcast, storage, server, and communication applications. The device is also RoHS compliant, and is available in both a Through-Hole or Surface-Mount package.

Jitter Considerations

Jitter is one of the key performance parameters of the SL23EP08SC-3T. The jitter performance of the device is excellent, allowing for use in applications requiring high clock accuracy or in general-purpose applications where jitter can degrade system performance. The jitter of the SL23EP08SC-3T is also very low, as the device has been designed to minimize output jitter and improve EMC performance.

The input clock frequency and the output frequency of the device also have an impact on the jitter performance. The jitter performance of the SL23EP08SC-3T is improved as the input frequency increases, while the output frequency of the device is also important as the spread of frequencies eases the effects of jitter.

Conclusion

The SL23EP08SC-3T clock generator is a Single-Ended Programmable Spread-Spectrum Clock Generator (SSCG) that is designed to minimize output jitter and improve electromagnetic compatibility performance. It utilizes a single-ended spread-spectrum integrated circuit (SSIC) to generate frequencies from 0.1 MHz up to 200 MHzwith excellent jitter performance. It is suitable for use in networking, digital video and broadcast, storage, server, and communication applications, and is RoHScompliant. The jitter performance of the SL23EP08SC-3T is also very low, making it suitable for both general-purpose applications where jitter can degrade system performance, and for applications requiring high clock accuracy.
