SI5338Q-B04069-GMR

The SI5338Q-B04069-GMR is a clock/timing specific application integrated circuit (IC) designed to provide higher frequency and signal accuracy over traditional low-frequency solutions. With its multiple output frequency dividers, it can generate similar or different frequencies as needed. Its low jitter and high signal integrity make it suitable for timing sensitive applications in the digital domain such as communication, audio and telecom systems.

The SI5338Q-B04069-GMR is based on a master clock source. It produces one or more independently-adjustable clock outputs based on the input clock frequency. By removing the input clock divider, the user can adjust the first output clock frequency of the IC to the required frequency for a particular application.

The SI5338Q-B04069-GMR has a phase-locked loop (PLL) circuit to ensure synchronization between the output clock frequency and the incoming clock. PLL works by comparing phase of the input clock to the phase of a stable reference clock and adjusts the phase of the output clock accordingly. This ensures that the output clock is phase and frequency locked to the input clock, ensuring the highest accuracy without introducing noise or jitter.

The SI5338Q-B04069-GMR also has five output clock dividers. Each divider divides the output clock frequency by two, four, eight, sixteen, or thirty two. By utilizing the divider outputs, the user can produce multiple frequencies of the same source clock. This allows the user to select the appropriate clock frequency for different applications while still maintaining excellent signal integrity.

The SI5338Q-B04069-GMR also has an integrated jitter and noise reduction circuit. This circuit contains both an analog low pass filter (LPF), and a digital filter (DF) to reduce the jitter and noise in the output frequency. The LPF reduces the jitter from the output clock in the frequency range from 20 MHz - 400 MHz. The DF filters out signals that are outside the programmed frequency range, and reduces the pulse jitter to less than 0.3 ps.

The SI5338Q-B04069-GMR also has various power saving modes to reduce power consumption when the clocks are not needed. The device can be put into a sleep state when the output clocks are not required, and it can be awoken from the sleep state when the clocks are required. The device also has an low-power consumption mode that reduces power consumption even further when the output frequencies are at their lowest.

All in all, the SI5338Q-B04069-GMR integrated clock/timing IC is a cost effective solution for applications requiring high frequency and signal accuracy. With its multiple output clock dividers, phase-locked loop circuit, and integrated jitter and noise reduction circuit, it provides stable and reliable timing signals in the digital domain. The power saving modes make it suitable for various power sensitive applications as well.
