SI5350A-B05783-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5350A-B05783-GTR is a factory-programmed 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 for both core and output buffers. It features low output period jitter typically below 70 ps pp and supports configurable spread spectrum to reduce EMI. The component is housed in a 20-QFN package and accepts a fixed-frequency crystal reference of 25 MHz or 27 MHz.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple independent clock frequencies from a single crystal reference

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B05783 suffix using ClockBuilder Pro software or official Skyworks documentation. Confirm that the 20-QFN package dimensions and thermal characteristics align with the target PCB layout requirements before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a custom frequency plan requiring up to eight outputs is needed without I2C reconfiguration overhead. Ensure the application can accommodate the required 25 MHz or 27 MHz crystal reference. Verify that the output drive strength and load capacitance requirements are met by the default high drive setting.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5350 family of factory-programmable clock generators. It serves as a cost-effective replacement for multiple discrete crystals and oscillators. The 'B' designation indicates it is preprogrammed at the factory, distinguishing it from blank versions that require user configuration.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory-programmed variants within the Si5350A family such as SI5350A-Bxxxxx-GM or SI5350A-Bxxxxx-GT, provided the pin count and output configuration match the design requirements.
