Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix 'DWG' to confirm the tape-and-reel or tube packaging variant intended for your assembly process. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for end-of-life notices or obsolescence announcements, as availability may be limited. Ensure the 20-SOIC footprint matches your PCB layout constraints. Validate that the 3.3V supply voltage aligns with your system's power architecture.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a 3.3V low-voltage ECL solution is required for generating four differential clock outputs. Compare the 50 ps jitter specification against system timing budgets to ensure signal integrity requirements are met. Consider the 54 mA supply current for thermal management and power budget calculations. Verify that the 1 GHz maximum frequency covers the highest harmonic or fundamental frequency needed. Evaluate the 20-SOIC package size against available board space compared to alternative packages like QFN or TSSOP.
