Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to confirm interface type and factory programming status. Confirm that the A15666 sequence ID matches the required frequency plan. Ensure environmental compliance requirements are met before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single PLL architecture with multiple synthesizer outputs is required. Verify that the 1.3 GHz maximum output frequency meets system needs. Consider the 72-QFN package dimensions for PCB layout constraints. Use ClockBuilder Pro software to validate the specific frequency configuration.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5361 family, which features one DSPLL and two MultiSynths. It differs from the Si5362 (two DSPLLs) and Si5363 (three DSPLLs). The 'A' grade indicates standard performance specifications. The 'GM' suffix denotes the 72-lead QFN package with extended temperature range capabilities.
