Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm tape and reel packaging and factory preprogramming status. Confirm that the component meets RoHS-6 compliance standards and check for any product change notifications or discontinuance notices associated with this specific part number revision before finalizing procurement plans.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when four independent output clocks are required with a maximum frequency limit of 350 MHz. Ensure the application requires fractional synthesis capabilities rather than integer-only modes. Verify that the system design accommodates the 44-QFN 7x7 mm package dimensions and provides adequate thermal management for the specified operating temperature range.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component is part of the Si5345/44/42 Rev D series, which utilizes MultiSynth and DSPLL technologies. The Si5344 variant specifically offers four inputs and four outputs, distinguishing it from the ten-output Si5345 and two-output Si5342 models within the same family.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Compatible substitutes include other SKUs within the Si5344 family such as SI5344A-D-GMR or SI5344B-D-GMR, provided they meet the specific frequency and feature requirements.
