It is part of the Clock Generator and Jitter Attenuator family, and offers a wide range of features and benefits to meet the demands of today’s clock and timing designs. This article provides an overview of the SI5338Q-B06770-GMR application field and working principle.

Application Field

The SI5338Q-B06770-GMR is a comprehensive system clock generator and jitter attenuator optimized to provide reliable and low-jitter clock distribution to multiple ASICs. It is designed to easily manage clock frequencies, multipliers and dividers, excellent jitter attenuation and EMI reduction functions. By providing the necessary infrastructure to facilitate clock distribution, the SI5338Q-B06770-GMR ensures that clock-dependent processes are reliable and cost-effective.

The SI5338Q-B06770-GMR also offers a number of additional benefits. It has advanced jitter attenuation capabilities that allow for reliable clock multiplication and distribution. Its EMI Reduction Inputs (ERI) reduce noise from interfering signals by passing them through a low-pass filter. Its Spread Spectrum Frequency Hopping (S-SFH) offers further noise reduction and allows for jitter to be spread across multiple frequencies. Finally, its multiple ports and programmable clock outputs offer further flexibility in setting the clock rates required for critical system timing processes.

Working Principle

The SI5338Q-B06770-GMR works on a reference clock, typically an oscillator or an external clock. The reference clock is then divided and multiplied to create the desired output frequency. The clock and timing components also operate on a set of internal registers, allowing the user to program the internal settings and generating the required frequency. Spread spectrum frequency hopping is then used to spread the jitter over multiple frequencies, while the EMI Reduction Inputs (ERI) are enabled to reduce noise from interfering signals.

The SI5338Q-B06770-GMR can generate a variety of output clocks and up to four spread-spectrum outputs simultaneously. It features a wide range of input and output frequency options, as well as various Slew Rate Control and Clock Stretching outputs for controlling high frequency signals.

The SI5338Q-B06770-GMR can also be used for established clock and timing applications, such as high-speed networking, communications and storage, or for applications requiring high-precision timing, such as applications requiring synchronization between multiple devices. In these cases, the SI5338Q-B06770-GMR can be used to manage the timing of multiple transceivers, allowing them to synchronize quickly and accurately to ensure optimal performance.

In short, the SI5338Q-B06770-GMR is an advanced, highly flexible clock generator and jitter attenuator, ideal for clock and timing applications in high-performance designs. Its comprehensive feature set allows it to meet the requirements of a wide variety of applications and use cases, while its advanced jitter attenuation, EMI reduction and Spread Spectrum Frequency Hopping functions ensure that clocks and timing signals remain reliable, accurate and low-jitter.
