SI5347A-B03294-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5347A-B03294-GM is a factory preprogrammed jitter attenuator from Skyworks Solutions, utilizing four independent Dual-Source Phase-Locked Loops (DSPLLs). It operates within a 64-lead QFN package measuring 9x9 mm. The device supports input frequencies up to 750 MHz and generates output frequencies ranging from 100 Hz to 720 MHz. It features ultra-low jitter performance of 95 fs rms and includes in-circuit programmable non-volatile memory for configuration storage.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific B03294 suffix against official Skyworks documentation to confirm the exact preprogrammed frequency plan and configuration parameters. Factory preprogrammed devices require validation of the unique numerical sequence ID assigned by ClockBuilder Pro software to ensure compatibility with target system requirements.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when high integration and independent timing paths are required. The Si5347A variant supports differential outputs up to 720 MHz. Ensure the application utilizes the 64-QFN package form factor and requires the specific jitter attenuation characteristics provided by the fourth-generation DSPLL technology.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5347 family, which offers quad DSPLL capabilities. It differs from the Si5346, which provides dual DSPLLs in a smaller 44-QFN package. The 'A' designation indicates support for higher output frequencies compared to the 'B', 'C', or 'D' grades.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Si5347A-D-GM is a base prototype version of the same package and grade. Si5347B-D-GM is an alternative grade supporting lower maximum output frequencies.
