Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the B suffix against the required application frequency plan. Confirm that the QFN-44 package dimensions align with the PCB footprint design. Ensure compatibility with the I2C or SPI serial interface protocols used in the system architecture before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when four independent clock outputs are required with ultra-low jitter specifications. The Si5340D variant supports output frequencies up to 350 MHz; verify that this limit meets the target application requirements. Consider the Si5341 family if more than four outputs or higher frequency capabilities are necessary for the design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5340 Rev D family of clock generators. It shares architectural similarities with the Si5341 series but provides four outputs instead of ten. The device integrates digital control interfaces and non-volatile memory, distinguishing it from fixed-frequency oscillators. It is designed to simplify clock tree designs by replacing multiple discrete timing components.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements within the same package include other Si5340 variants with different factory programming. For pin-compatible upgrades requiring additional outputs, consider the Si5341 family. Verify that any substitute maintains the required jitter performance and output format compatibility.
