Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Verification of current availability through authorized distributors is required, as stock levels are limited or nonexistent. Buyers must confirm RoHS compliance status and moisture sensitivity level details directly with suppliers before procurement. Alternative sourcing strategies should be evaluated due to the discontinued status.

Selection Notes

Engineers selecting this part should verify compatibility with PCIe Gen2 specifications and ensure the 484-lead FCBGA footprint fits the design constraints. The requirement for multiple voltage domains (1V, 2.5V, 3.3V) must be addressed in the power delivery network design. Consideration of the obsolete status is critical for long-term production viability, necessitating potential redesigns for future projects.

Part Context

The 89H32NT24AG2ZCHLI belongs to the IDT 89H series of PCIe switches, designed for demanding enterprise and industrial networking applications. This specific variant represents a 32-lane, 24-port configuration within the Gen2 generation lineup. It shares architectural similarities with other models like the 89H24NT24G2 but offers higher port density. The series is known for low latency and internal buffering optimized for large payloads.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult Renesas Electronics for recommended next-generation replacements or equivalent components that meet the same 32-lane, 24-port PCIe Gen2 specifications.
