SI5350A-B02848-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B02848-GT is a factory-programmable, any-frequency CMOS clock generator manufactured by Skyworks Solutions. It utilizes a MultiSynth architecture to generate up to three non-integer-related frequencies from 2.5 kHz to 200 MHz with 0 ppm error. The device operates on a single supply voltage of 1.8 V, 2.5 V, or 3.3 V and features low output period jitter typically less than 70 ps peak-to-peak. It accepts a fixed-frequency crystal reference of 25 MHz or 27 MHz and is housed in a compact 10-MSOP package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple independent, non-integer-related clock frequencies from a single crystal reference
• Configurable spread spectrum modulation for electromagnetic interference reduction
• Supports glitchless frequency transitions via user-configurable control pins
• Provides separate core and output voltage supplies for flexible level translation

Clock Generators, PLLs, Frequency Synthesizers Applications

• Replacing discrete crystals and oscillators in cost-sensitive designs
• Audio/video equipment and set-top boxes
• Networking and communication systems
• Servers and storage arrays

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed frequency configuration against system requirements before procurement. Confirm that the 10-MSOP package meets board space constraints. Ensure the selected crystal matches the internal load capacitance settings defined in the ClockBuilder Pro design file.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when three distinct clock outputs are required from a single source. Verify that the target frequencies fall within the 2.5 kHz to 200 MHz range. Check if the pin-controlled frequency select feature is needed for dynamic switching between two predefined frequencies on the same output.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of programmable clock generators. Unlike I2C-configurable variants, this model uses direct pin control for configuration options such as power down and frequency selection. It serves as a drop-in replacement for standard crystal oscillators in embedded systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory-programmed Si5350A variants with different output counts, such as the 4-output 16-QFN or 8-output 20-QFN versions, provided the pinout and package dimensions are compatible with the existing footprint.
