SI5340A-B04136-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5340A-B04136-GM is a programmable clock generator from the Si5340 series by Skyworks Solutions. It features four outputs capable of generating any frequency up to 1.028 GHz with ultra-low jitter of 90 fs rms. The device utilizes MultiSynth fractional synthesizer technology and supports input frequencies up to 750 MHz. It operates on a supply voltage between 1.71 V and 3.47 V, consumes 115 mA or 120 mA depending on configuration, and functions within an industrial temperature range of -40°C to +85°C. The component is housed in a QFN-44 package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix B04136 against official Skyworks documentation to confirm the exact pre-programmed frequency set, as this suffix defines the custom factory configuration. Confirm RoHS compliance status and lead times through authorized distributors, as availability varies by region and production cycle.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a fixed-frequency solution is preferred over runtime reconfiguration. Ensure the required output frequencies fall within the 100 Hz to 1.028 GHz range. Verify that the input source matches the supported differential, LVCMOS, or crystal inputs specified for the Si5340A variant.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5340 family of low-jitter clock generators. It shares architectural similarities with the Si5341 but offers four outputs instead of ten. The 'GM' suffix indicates a Green (RoHS compliant) QFN-44 package, while 'B04136' denotes a specific factory-programmed frequency plan.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5340A variants with different factory presets (e.g., SI5340A-Bxxxxx-GM). For pin-compatible upgrades with more outputs, consider the Si5341 series, though pin counts differ.
