Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to confirm factory preprogramming details. Confirm availability status through authorized distributors as supply conditions may vary. Ensure the component meets RoHS-6 compliance requirements for your manufacturing process. Validate that the 44-QFN package dimensions align with your PCB land pattern specifications before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when four output clocks are required with frequencies up to 350 MHz. The Si5344D variant specifically limits output frequency compared to the Si5344A version which supports up to 1028 MHz. Ensure the application requires integer and fractional synthesis modes supported by the Rev D architecture. Verify that the 44-QFN footprint fits the design constraints compared to the larger 64-QFN options available in other family members.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345/44/42 Rev D series, which integrates DSPLL and MultiSynth technologies for high-performance clock generation. The Si5344 variant specifically provides four inputs and four outputs, distinguishing it from the ten-output Si5345 and two-output Si5342 models. All devices in this series share common functional blocks including the serial interface and non-volatile memory configuration capabilities.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Si5344B-D-GMR offers similar functionality but may differ in specific factory programming configurations. Si5344A-D-GM provides higher maximum output frequencies up to 1028 MHz if the application requires broader frequency ranges. Verify pin compatibility and software configuration files when substituting these parts to ensure seamless integration.
