The SI5348A-B-GM is a Clock/Timing device that is especially useful in a wide range of applications that require complex clock function and generation. This includes applications such as networking, computer architecture, digital transmission, and telecommunications systems. This is accomplished by leveraging the clock generators, PLLs (Phase Locked Loops), and frequency synthesizers found in the SI5348A-B-GM.The SI5348A-B-GM is a clock generator, PLL and frequency synthesizer system all in one package. This unit integrates the components necessary to generate all the clock functions necessary, with each component having features that are optimized for the specific application.At the heart of the SI5348A-B-GM’s operation is a step-by-step process of synthesizing the clocks. First, it takes the input frequency and creates a Reference Clock from it. This is done using a Voltage Controlled Crystal Oscillator (VCXO). The output from the VCXO is used to generate other frequency-based output clocks, such as Multiplication Clocks (MCs).In order to achieve different frequencies, the Multiplication Clocks are then fed into digital divide clocks (or divider clocks), and this allows the SI5348A-B-GM to different frequencies by various amounts.The other component of the SI5348A-B-GM is its PLL – a digital system to keep the various outputs in synchronization over a wide range of environmental conditions. The purpose of the PLL is to act as a type of digital loop filter. It continuously adjusts the clock’s output frequency according to the signal from the reference input clock, a maximum reference frequency which can be divided down and output signal frequencies, and a range of settings for the other signal outputs. The SI5348A-B-GM uses a digitally-controlled oscillator to optimize the PLL to provide a high degree of accuracy in the system’s clock outputs. This digital loop filter keeps the outputs from drifting due to temperature variation, required process scalability, and other effects that can cause system instability.The SI5348A-B-GM can satisfy the needs of applications who need a wide variety of clock functions, as well as frequency-synchronized operations. It is ideal for systems that require precise clock functions such as telecommunications applications, digital networks, and computer architecture. With its range of clock, PLL, and frequency synthesizer functions, the SI5348A-B-GM is the ideal solution for all of these applications.
