Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory pre-programmed configuration for the -B04199 suffix against design requirements using ClockBuilderPro software. Confirm package availability and lead times through authorized distributors as stock levels vary. Ensure ESD protection protocols are followed during handling due to the sensitivity of the CMOS internal circuitry.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when four independent clock outputs are required with sub-100 fs jitter performance. Compare against the SI5341 series if ten outputs are needed instead of four. Ensure the application supports the QFN-44 footprint and thermal dissipation requirements. Verify that the required output voltage standards (LVDS, LVPECL, etc.) are compatible with the programmable amplitude settings.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si534x family of low-jitter clock generators. It serves as a 'clock tree on a chip,' replacing multiple discrete oscillators and buffer ICs. The Si5340 variant specifically provides four outputs, distinguishing it from the ten-output Si5341 models while sharing similar jitter performance and synthesis architecture.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements include other Si5340A variants with different factory programming suffixes. For pin-compatible upgrades requiring more outputs, consider the Si5341 series. Generic clock generators lacking MultiSynth technology may not achieve the specified 90 fs jitter performance.
