Working Principle

The working principle of SI5338Q-B02007-GMR clock multiplier and jitter cleaner is relatively simple. This device takes in an input frequency and multiplies it internally to generate output frequency signals. The device also filters the jitter of two input clocks, improving their accuracy.The device has two main parts: the input divider and the output divider. These two dividers are adjustable for different output frequencies. The input divider is the part of the device which divides the input frequency. It can be adjusted to produce a lower input frequency. The output divider is the part of the device which divides the output frequency. It can be adjusted to produce a higher output frequency.The SI5338Q-B02007-GMR also contains a low-jitter PLL (Phase Locked Loop) that is used to synchronize the device\'s internal oscillator to the input clock, while the jitter filter cleans up jittered signals. That is, the jitter filter improves the accuracy of the output clock. The device also contains a voltage-controlled oscillator which can be used to generate a wide range of frequencies.The SI5338Q-B02007-GMR enables customers to reliably generate multiple fractional frequency outputs on either single-ended or differential LVDS/LVPECL formats. The device is designed for applications requiring multiple and fractional frequency clocks. It is especially useful in space-constrained systems.

Conclusion

The SI5338Q-B02007-GMR clock multiplier and jitter cleaner is a versatile and capable single-chip device that is able to generate multiple fractional frequency outputs on either single-ended or differential LVDS/LVPECL formats.
