Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the current lifecycle status before procurement, as official records indicate this specific part number may be subject to termination or limited availability. Confirm that the TQFP-52 package dimensions match the target PCB footprint. Ensure the 3.3 V operating voltage aligns with the system power rails. Check for moisture sensitivity classification requirements during storage and handling.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low-jitter, multi-phase clock signals are required without external timing components. The integrated PLL simplifies design compared to discrete solutions. Verify that the 200 MHz maximum frequency meets the system's timing requirements. Consider the thermal performance within the specified -40°C to +85°C range for the intended application environment.

Clock Generators, PLLs, Frequency Synthesizers Part Context
