Procurement Notes

Verify the specific suffix and revision level against the manufacturer's current datasheet to ensure compatibility with design requirements. Confirm packaging details and environmental compliance status prior to ordering. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Check for any recent lifecycle notices or obsolescence warnings associated with this specific model variant.

Selection Notes

Select this component when a wide variety of output voltage standards and programmable frequency scaling are required. Ensure the system power supply aligns with the 3 V to 3.6 V operational window. Verify that the thermal environment remains within the specified -40°C to +85°C range. Consider the TSSOP-48 footprint constraints during PCB layout planning to maintain signal integrity at high frequencies.

Part Context

The CDC516DGG is part of Texas Instruments' broader CDC516 family of clock drivers designed for complex timing architectures. This series provides versatile solutions for generating and distributing clock signals in systems requiring precise synchronization. The DGG suffix specifically denotes the TSSOP-48 surface-mount package, distinguishing it from other physical form factors available within the same functional family.
