SI5350A-B05288-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5350A-B05288-GM is a factory-programmable CMOS clock generator designed to replace discrete crystals and oscillators. It utilizes a PLL and MultiSynth architecture to generate up to eight non-integer-related frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. The device supports independent core (VDD) and output (VDDO) supply voltages of 1.8 V, 2.5 V, or 3.3 V. Key electrical characteristics include typical period jitter below 70 ps pp and low power consumption of approximately 25 mA at the core supply.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Audio/video equipment and gaming consoles
• Printers, scanners, and projectors
• Residential gateways and networking communication devices
• Servers and storage systems

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the suffix B05288 using ClockBuilder Pro software. Confirm that the required package type matches the design constraints, as the Si5350A family offers varying output counts across MSOP and QFN form factors. Ensure the selected part aligns with the intended voltage levels and crystal reference specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a cost-effective solution is needed to replace multiple discrete clock sources. Verify that the application requires pin-controlled features rather than I2C programming, as the 'A' variant lacks digital interfaces. Check if the required number of outputs fits within the available package options, noting that higher output counts require larger packages.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5350 family of clock generators manufactured by Skyworks Solutions. It is distinguished from the Si5351 series by its lack of I2C programmability, relying instead on factory pre-programming and external control pins. The 'B' designation indicates a factory-configured unit rather than a blank device.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must be other Si5350A variants with identical factory programming configurations. Cross-referencing with Si5351 models is not recommended due to the absence of I2C interfaces in the Si5350A. Verify package compatibility if substituting between MSOP and QFN footprints.
