The SI5383A-D07172-GM belongs to the family of clock generators and frequency synthesizers.

It provides a flexible solution to clocking and timing requirements specific to high-speed applications, allowing users to select and configure the clock generation needed to operate the system. It includes a wide range of features such as multiple output types including LVDS, LVCMOS, HCSL, and CML, adjustable output frequency and spread-spectrum, a wide frequency range from 25 MHz to 1 GHz and full ClockBuilder Pro software support for ease of configuration.

The SI5383A-D07172-GM is suitable for a variety of markets and applications such as military, aerospace, instrumentation, satellite, automotive, and communications.

The working principle of the SI5383A-D07172-GM is based on the same Phase Locked Loop (PLL) principle used by all other clock generators. The PLL consists of a Voltage Controlled Oscillator (VCO) and a phase/frequency detector (PFD) whose outputs are connected to each other. The input reference clock leads to a signal on its input and the feedback signal from the VCO output is compared with the input signal.

When the two signals match, the current generated by the PFD maintains the frequency and phase of the VCO output, producing an output signal (Output Clock) with the same itemization as the input signal – both frequency and phase. The frequency of the output clock is adjustable by varying the supply voltage of the VCO.

The SI5383A-D07172-GM includes a range of options to help customers to easily customize the output clock. Users can configure the chip to select the output type, spread-spectrum, frequency range and output division ratio. This allows for a great deal of flexibility in the clock frequency and types.

In addition, the SI5383A-D07172-GM provides an optional Spread Spectrum Clock Generator (SSCG) mode which reduces the clock emissions by spreading the clock spectrum across a wider frequency range. It is compliant with EMI Reduction regulations and supports the most stringent system requirements.

To configure the SI5383A-D07172-GM, customers can use Silicon Labs’ ClockBuilder Pro software. This software helps customers to easily create and customize the clock setup to match their applications. Customers can also use any of Silicon Labs\' EFM32 or EFM8 families of microcontrollers to use as a development platform when using ClockBuilder Pro.

The SI5383A-D07172-GM is a reliable and cost-effective clock generator solution for many demanding applications. It provides users with flexibility in clock type selection, spread-spectrum, frequency range selection and output division ratio selection. ClockBuilder Pro removes any difficulties in setting up the chip and its support for the EFM32 and EFM8 microcontroller families simplifies the development process.
