Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm factory pre-programmed configuration details. Confirm availability status as distribution channels may list this component as discontinued or limited stock. Ensure compatibility with ClockBuilder Pro software settings before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when multiple independent low-jitter clock domains are required from various input sources. The quad DSPLL architecture allows routing any input to any output via a flexible crosspoint. Verify that the required output frequency range fits within the 720 MHz differential limit. Consider the 64-QFN package size for PCB layout constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5347 family, which utilizes fourth-generation DSPLL technology. It serves as a high-performance solution for applications demanding maximum integration and independent timing paths. The device distinguishes itself through its ability to handle any input-to-output frequency conversion while maintaining strict jitter specifications.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations
