Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix B03764 against official Skyworks documentation to confirm factory preprogrammed configuration details. Ensure compatibility with ClockBuilder Pro software settings for the designated NVM data. Confirm package type and temperature range specifications match system requirements before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low jitter performance below 350 MHz is required with only two output channels. The Si5342D variant specifically limits output frequency compared to the A or C variants. Verify that the application requires the 44-QFN package size and operates within the specified -40 to +85 °C temperature range.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5342 Rev D series, which combines DSPLL and MultiSynth technologies. It serves as a compact alternative to the higher-channel Si5344 and Si5345 devices. The 'D' suffix indicates a maximum output frequency limit of 350 MHz, distinguishing it from other family members capable of higher frequencies.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements within the same package include SI5342A-D-GM, SI5342B-D-GM, and SI5342C-D-GM. These parts share the same pinout but differ in maximum supported output frequency ranges. Verify that the replacement part's frequency capabilities meet the design requirements.
