The functional blocks of the SI5335A-B07800-GMR are of low power consumption and with such a feature, power needs of the target system are reduced significantly.

Applications

The SI5335A-B07800-GMR can be used in various clock and frequency synchronization applications such as telecommunication, industrial control, and consumer electronics. This clock generator is ideal for frequency-synchronized soft-core processors and processors used in real-time systems. It can also be used for digital signal processing (DSP), clock-and-data recovery (CDR), clock distribution, and network synchronization.

Working Principle

The basic working principle of the SI5335A-B07800-GMR is the same as any other PLL based clock generator. It uses a reference clock (crystal) to generate the output clock signal. The input reference clock is sent to a phase detector which compares the signal with a voltage-controlled oscillator (VCO). The signal from the phase detector is then sent to a low pass filter which converts the signal into a control voltage that is used to control the frequency of the output clock signal.

The output clock signal is then sent to a frequency divider which divides the frequency of the clock signal by a certain amount. This allows the signal to be output at a rate more suitable for the application. For example, a 512Hz clock signal can be divided down to a 64Hz signal that can be used for microcontroller applications.

Conclusion

The SI5335A-B07800-GMR is an Any-Frequency Clock Generator that enables the development of next-generation time-sensitive systems by providing a solution for efficiently generating high-accuracy clock signals that run along with the system. Its clean output signals and low power consumption make it ideal for a variety of applications such as telecommunications, industrial, and consumer electronics.
