The SI5338B-B07751-GMR is a versatile clock generator which can be used in a variety of applications. It is one of the popular members of Silicon Labs’ family of programmable clock ICs with the highest number of configurable options available. It is designed for high performance, high integration and low cost applications, typically found in any application where there is a need for accurate timing, such as: automotive audio systems, computing, industrial automation, robotics, industrial process control, and military/aerospace applications. The SI5338B-B07751-GMR provides a number of features, including configurable outputs, programmable phase-shifting, set-and-forget operation, frequency synthesis, spread spectrum output, and jitter attenuation. It is also capable of supporting a wide range of frequencies and functionalities.

The SI5338B-B07751-GMR is based on the patented Silicon Integrated Systems Corporation (Simplis) architecture, which is a powerful but simplified implementation of clock generation. The architecture supports frequencies ranging from a few kilohertz (kHz) up to 1 gigahertz (GHz), and can be configured for a variety of applications. The architecture is designed to provide superior jitter performance, excellent jitter attenuation, and superior phase noise performance. The architecture also allows for a high degree of integration, which translates into reduced costs in components as well as board space.

In order to achieve its excellent performance characteristics, the SI5338B-B07751-GMR utilizes a multi-stage clocking architecture. The first stage is the master clock which is generated using an on-chip voltage controlled oscillator (VCO) or an external reference clock. The master clock is then used to drive the on-chip phase-locked loop (PLL), which provides a clean, stable clock signal to the other stages. The other stages of the design are responsible for generating the specific output frequencies and jitter-attenuators, if needed. Once the output frequency is generated, it is buffered and connected to the clock output buffer.

The output of the SI5338B-B07751-GMR can be configured to deliver an array of frequencies from megahertz (MHz) up to 1GHz with low jitter and with jitter attenuation. The output of the clock generator can be tailored for specific requirements, for example for generating sub-gigahertz (GHz) frequencies within the range of 1GHz. This is especially useful for applications that require ultra-low-jitter clock signals, such as automotive communications systems.

The SI5338B-B07751-GMR also offers a variety of other features, such as a spread spectrum modulation, an integrated voltage regulator and a wide temperature range operation. Spread spectrum modulation technology is useful in applications that require low EMI such as automotive electronics. The spread spectrum modulation can also be used to reduce the peak-to-peak jitter of the generated clock signal. The integrated voltage regulator provides adjustable power supply voltage, which can be set to the required voltage level for the specific application, while the wide temperature range operation enables the clock generator to operate in various environmental conditions.

In summary, the SI5338B-B07751-GMR is a versatile clock generator which can be used in a variety of applications where accurate timing is essential. The architecture allows for a high level of integration, cost-efficiency and excellent jitter and phase noise performance. The SI5338B-B07751-GMR is specifically designed for applications requiring sub-gigahertz frequencies, and the spread spectrum modulation feature and integrated voltage regulator ensure compatibility with various automotive communications protocols. This clock generator is a perfect solution for applications that require high performance, low cost and integration.
