Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix B03995 against official Skyworks documentation to confirm the exact pre-configured frequency set and output format. Ensure compatibility with system power supply rails within the 1.71 V to 3.63 V range. Check for moisture sensitivity level requirements during storage and handling. Confirm package type is QFN-24 as specified for this series variant.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a compact solution is needed for generating multiple distinct clock frequencies from a single reference. It replaces multiple discrete oscillators and buffers. Consider the I2C or SPI configuration method if dynamic frequency changes are required. Evaluate thermal dissipation in the QFN-24 package under maximum load conditions.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5340 family of ultra-low-jitter clock generators. It shares architectural similarities with the Si5341 but offers four outputs instead of ten. The device integrates a wide-band PLL and proprietary MultiSynth technology to eliminate the need for external crystal oscillators in many applications, simplifying the clock tree design.
