Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Verification of availability should focus on distributor surplus stock or authorized secondary market channels rather than direct manufacturing supply. Confirm RoHS compliance status and check for specific lot date codes if historical units are sourced. Ensure that any replacement strategy accounts for the discontinued status to prevent long-term supply chain risks.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a single differential or single-ended input requires expansion into twenty distinct output clocks. It is suitable for designs requiring mixed voltage levels across outputs without external level shifters. Consider the 100-LQFP footprint constraints during PCB layout. Verify that the required operating frequency does not exceed the 400MHz maximum specification for the selected package variant.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The ISPPAC-CLK5520V-01T100C belongs to the ispClock family of clock generators. It shares architectural similarities with the ISPPAC-CLK5620 series but differs in specific pin configurations and supported I/O standards. This model is specifically engineered for applications needing high fan-out capabilities from a single source while maintaining signal integrity through integrated buffering and programmable delay elements.
