Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix GMR indicates tape-and-reel packaging when sourcing. Confirm that the B04342 designation corresponds to the required factory-programmed frequency plan, as this variant is not universally stocked. Cross-reference the datasheet for humidity sensitivity handling requirements during assembly. Ensure compatibility with the Si5341-D-EVB evaluation kit for initial validation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when ten synchronized clock signals are required with minimal phase noise. Compare against the SI5341A-D-GMR if a generic development version is preferred over a fixed-frequency solution. Consider the QFN-64 package dimensions for PCB layout constraints. Verify input reference frequency compatibility up to 750 MHz before finalizing the design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5341 series of low-jitter clock generators designed for demanding digital systems. It utilizes MultiSynth technology to provide flexible frequency synthesis without external components. The device integrates voltage-controlled oscillators and synthesizers on a single chip, reducing board space compared to discrete solutions.
