SI5350A-B05159-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B05159-GMR is a factory-programmable CMOS clock generator manufactured by Skyworks Solutions. 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 operates on a single supply voltage of 1.8 V, 2.5 V, or 3.3 V and accepts a 25 MHz or 27 MHz crystal reference. Key electrical parameters include a typical core supply current of 25 mA (8 outputs enabled) and output period jitter below 70 ps peak-to-peak. It supports glitchless frequency changes, configurable spread spectrum, and static phase offsets.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple independent clock frequencies from a single crystal reference
• Supports glitchless frequency transitions and configurable spread spectrum for EMI reduction
• Features user-configurable control pins for power management and output selection
• Provides separate voltage supplies for core logic and output buffers

Clock Generators, PLLs, Frequency Synthesizers Applications

• HDTV, DVD/Blu-ray, and set-top box systems
• 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 B05159 suffix using ClockBuilder Pro software. Confirm that the package type matches the required number of outputs, as the Si5350A family offers 3, 4, or 8 output variants in different packages. Ensure the design uses the correct crystal load capacitance settings provided in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when replacing multiple discrete crystals or oscillators to reduce board space and cost. Choose the appropriate package based on the required number of outputs: 10-MSOP for three outputs, 16-QFN for four outputs, or 20-QFN for eight outputs. Verify that the application requires pin-controlled features rather than I2C programmability, which is reserved for the Si5351 series.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350A family of factory-programmable clock generators. Unlike the Si5351 series, which supports I2C reconfiguration, the Si5350A is configured at the factory via ClockBuilder Pro and controlled via dedicated GPIO pins. The GMR suffix indicates tape and reel packaging suitable for automated surface-mount assembly.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include other Si5350A-Bxxxxx-GMR parts with different factory programming but identical electrical characteristics. For I2C-reprogrammable alternatives, consider the Si5351A-Bxxxxx-GMR series, noting the difference in control interface.
