Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix B03759 against official Skyworks documentation to confirm factory-programmed parameters. Custom part numbers indicate pre-configured settings; ensure these match design requirements before procurement. Check current availability status as custom parts may have limited stock or longer lead times compared to generic variants.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant when fixed, factory-programmed frequencies are preferred over field-programmable options. Ensure the required output formats (LVDS, LVPECL, etc.) align with the device's configurable capabilities. Verify that the input source matches the supported ranges: 25-54 MHz for crystals, up to 750 MHz for differential clocks, or up to 250 MHz for LVCMOS.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5341 series, which combines wide-band PLL with proprietary MultiSynth fractional synthesizer technology. The series is designed to replace multiple clock ICs and oscillators with a single device, offering a versatile platform for synthesizing integer and non-integer related frequencies on ten differential outputs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Generic replacements like SI5341A-D-GM require reprogramming via I2C/SPI or ClockBuilderPro software to achieve identical frequency outputs. Verify pinout compatibility and thermal characteristics when substituting. Ensure the replacement supports the same output voltage levels and drive strengths required by the target application.
