Procurement Notes

This specific part number (23S09E-1HDCGI8) is officially listed as obsolete and no longer manufactured by Renesas Electronics. Verification of current stock availability through authorized distributors is required before procurement planning. Designers should confirm end-of-life status and transition timelines directly with the manufacturer or authorized sales offices to ensure supply chain continuity.

Selection Notes

Due to the obsolete status of the 23S09E-1HDCGI8, selection should prioritize replacement components. Renesas recommends the 23S09-1HPGGI8 as a suitable alternative. Engineers must verify pin compatibility, electrical specifications, and package dimensions when transitioning to substitute parts to maintain system integrity without redesign.

Part Context

The 23S09 series comprises high-speed PLL clock buffers designed for zero-delay applications. The 'E' suffix typically denotes an enhanced or specific variant within the family, while '1H' indicates a high-drive version with faster rise and fall times compared to standard variants. These devices align input and output clock phases to minimize skew in high-speed data paths.

Replacement Considerations

Renesas recommends the 23S09-1HPGGI8 as the official replacement for the obsolete 23S09E-1HDCGI8. Users should evaluate the new part's package type and electrical characteristics against the original design requirements.
