Procurement Notes

This component is officially listed as obsolete by Renesas Electronics Corporation and is no longer manufactured. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific suffix 'W' and package type (Tape & Reel Standard Package: 2,500) when sourcing replacements or surplus inventory.

Selection Notes

Engineers selecting this part should note its specific support for PCIe Gen7 standards and 100MHz output pairs. The device requires a supply voltage between 2.375V and 3.63V. Input compatibility includes CML, ECL, LVDS, and LVPECL. Due to its obsolete status, alternative components with similar differential input/output characteristics and PCIe generation support must be evaluated for pin-to-pin or functional compatibility.

Part Context

The 853S9252 series belongs to Renesas' portfolio of high-speed clock buffers and drivers. These components are typically used in high-bandwidth data transmission systems requiring signal distribution and level shifting. The 853S9252 specifically targets next-generation peripheral component interconnect express standards, providing low-jitter buffering for critical clock paths in enterprise and industrial computing environments.

Replacement Considerations

As the 853S9252BKILF/W is obsolete, direct substitutes are not explicitly confirmed in public documentation. Designers should consult Renesas technical support for cross-reference recommendations or evaluate competing high-speed fanout buffers that support PCIe Gen7 and compatible input logic families.
