Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to confirm tape-and-reel packaging and factory pre-programming details. Ensure the custom configuration sequence matches the required design specifications before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a dual-DSPLL architecture with a maximum output frequency of 350 MHz is required. Verify that the 44-QFN package dimensions fit the PCB layout constraints. Confirm compatibility with the I2C or SPI serial interface requirements for system integration.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5346 Rev D family, which utilizes fourth-generation DSPLL technology. It serves as a compact alternative to the quad-DSPLL Si5347, offering similar jitter attenuation performance in a smaller form factor suitable for space-constrained designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The Si5346A-D-GM is a compatible variant within the same series but supports higher output frequencies up to 720 MHz. Verify if the lower frequency limit of the Si5346B meets the specific application requirements before substituting.
