It is ideal for designs that require ultra-low power operation and tight jitter budgets.

Application Fields

The SI5335B-B09008-GMR is well suited for a variety of clock generation applications, such as telecom and datacom systems. It is ideal for designs that require ultra-low power operation and tight jitter budgets. The device also features an on-chip crystal oscillator, which helps to reduce EMI for telecom and datacom applications. It can be used in high-end timing applications, where low jitter is key, such as network equipment, storage systems, and packet processing applications.

Working Principle

The SI5335B-B09008-GMR combines a clock generator and jitter attenuator into a single compact device. At the heart of the device is a Phase Locked Loop (PLL) block, which uses an input reference clock or frequency to generate a low jitter output clock. The PLL is designed to reduce jitter from the output clock by actively tracking and compensating for any variation in the input reference clock. It uses a “feed-forward” technique to reduce jitter, which senses any changes in the frequency or phase of the input reference clock, quickly makes the necessary corrections, and produces a clean, low jitter output clock.

The device also includes an on-chip crystal oscillator, which helps to reduce EMI for telecom and datacom applications. It can also be used as a clock source for timing generators in networking equipment and packet processing systems. The device features an integrated jitter attenuator, which can reduce jitter down to 200fs. The integrated PLL is designed to reduce the jitter from the input reference clock, and the on-chip jitter attenuator helps to further reduce jitter from the output clock. This allows the SI5335B-B09008-GMR to provide a superior jitter performance for demanding telecom and datacom applications.

Conclusion

The SI5335B-B09008-GMR from Silicon Labs is a high-performance clock generator and jitter attenuator combination. It is ideal for applications that require tight jitter budgets, ultra-low power operation, and an on-chip crystal oscillator. The integrated PLL can reduce jitter from the input reference clock and the on-chip jitter attenuator helps to further reduce jitter from the output clock. This allows the SI5335B-B09008-GMR to provide a superior jitter performance for demanding telecom and datacom applications.
