The SI5345A-B-GM is one of the most versatile clock generators on the market. It offers unprecedented levels of performance, accuracy and flexibility for a range of industries and applications. In this article we will take a look at its application field and working principle.

At the heart of the SI5345A-B-GM is an innovative ‘Tri-Clock Management’ core that enables it to support complex clocking architectures. This allows it to serve as a singular solution for multiple applications, from ultra-low power, low-frequency systems to high performance, multi-gigabit systems.

The SI5345A-B-GM is most commonly used for networking and communications applications, with its clock synthesizer providing a wide range of frequencies to support these needs. It also finds a home in industrial control and measurement applications, given its high frequency resolution and its ability to reduce time-to-market.

The working principle of the SI5345A-B-GM is simple yet clever. It uses fractional frequency synthesis, coupled with the Tri-Clock Management core, to generate the output. The core is essentially a synchronized clock output generator, generating multiple independent clock outputs at different frequencies with very low phase jitter.

These clocks can range from very low frequencies, such as 10 Hz, to very high frequencies, such as 2.4 GHz. To achieve this wide variety of frequencies, the SI5345A-B-GM utilizes both an Output Clock Source and an Input Clock Source.

The Output Clock Source is used to generate a single reference frequency, which is then divided or multiplied to generate the required output frequency. This approach is typically used for very low frequencies, such as those used in industrial control and measurement applications.

The Input Clock Source is then used to directly generate the required output frequency. This approach is typically used for higher frequency applications, such as those used in networking and communications.

In addition to generating the clock outputs, the SI5345A-B-GM also has a range of other features and functions. It is able to aggregate multiple inputs such as Ethernet, HDMI, and SATA and convert them into the appropriate clock outputs. It also offers a variety of resolution options, allowing designers to optimize their design for the most precise output.

The SI5345A-B-GM has a variety of programmable parameters, allowing it to be customized for specific customer requirements, such as system timing, low power operation and temperature compensation. This level of flexibility and scalability is unique in the industry.

In summary, the SI5345A-B-GM is a highly versatile clock generator, offering unparalleled levels of performance, accuracy and flexibility for a range of applications. Its innovative Tri-Clock Management core enables it to generate a wide variety of low and high frequencies, while also providing scalability and time-to-market advantages. Its range of features and functions, coupled with its programmable options and temperature compensation, make it the perfect solution for an array of industries and applications.
