Working Principle

The working principle of the SI5338A-B02499-GMR is based on the integration of a SAW oscillator with a digital phase locked loop (PLL). The device contains an oscillator for outputting a reference clock with a frequency range of 10-100 MHz. The resulting output is then fed into a digital PLL which adjusts the output frequency to meet the desired specifications.

The digital PLL works by first dividing down the reference clock to create a feedback signal. The resulting signal is then compared to the target output frequency.If the two signals are mismatched, the PLL will use an internal VCO (voltage controlled oscillator) to adjust the output frequency until the desired frequency is achieved.

Once the output frequency is matched, the PLL will lock to the output. It will then continuously compare the incoming reference frequency with the output frequency, and will adjust the output frequency if the two are mismatched.

Conclusion

The SI5338A-B02499-GMR is a versatile clock/timing component used in a wide range of applications. Its integrated SAW oscillator and digital phase locked loop provide precise frequency and phase synchronization for next-generation communications systems, machine vision, and medical imaging applications. The device contains ExactLocks™ technology for guaranteed reliable synchronization, which makes it an ideal choice for cost- and space-constrained systems.
