Working Principle

The SI5335D-B07027-GMR is a high-performance integrated circuit that combines both a reference oscillator and a multi-output programmable oscillator. The reference oscillator uses an on-chip MEMS oscillator to provide a highly stable reference clock. The MEMS oscillator is an electrostatically-driven device and offers superior stability even under extreme environmental conditions.The on-chip programmable oscillator circuitry then takes the reference clock and synthesizes a variety of high-performance, low-jitter, low-EMI output clocks. This process is done using a combination of phase-locked loops and digital frequency synthesis, allowing frequencies up to 400MHz with a wide tuning range. This high bandwidth and low jitter make it ideal for higher performance applications.Additionally, the SI5335D-B07027-GMR provides a programmable logic control input, allowing for pin control of output frequency and power consumption. This functionality is especially useful for applications that require programmability and/or dynamic frequency selection. The control of the oscillator’s power consumption can also be used to reduce overall system power consumption in applications that require high frequency synchronization.

Conclusion

The SI5335D-B07027-GMR is a highly versatile clock and timing integrated circuit that is suitable for a wide range of industrial, consumer, and portable applications. Its MEMS oscillator offers superior stability even under extreme environmental conditions, making it ideal for high-performance, low-EMI applications. The ability to program its output frequency, and consequently its power consumption, make it ideal for frequency hopping, dynamic frequency selection, or power-saving applications.
