Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized Skyworks distributors or official channels. Confirm the specific suffix matches the required frequency plan, as custom part numbers are generated per application. Check current lifecycle status, as this model may be discontinued or subject to limited availability. Ensure ESD protection protocols are followed during handling due to the sensitive nature of CMOS clock generation circuits.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when ten distinct clock outputs are required from a single source. Verify that the target frequencies fall within the supported range of less than 350 MHz for optimal jitter performance. Consider the QFN-64 package constraints for PCB layout. Evaluate power consumption requirements against the specified 115 mA or 120 mA operating currents. Confirm compatibility with available programming tools like ClockBuilderPro for customization.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component is part of the Si5341 family, which integrates wide-band PLLs with fractional synthesizers.
