89H48H12G3YCHLI8

Overview

The 89H48H12G3YCHLI8 is a 48-lane, 12-port PCI Express Gen3 system interconnect switch manufactured by Renesas Electronics. It delivers up to 96 GBps (768 Gbps) of switching capacity through integrated SerDes supporting 8.0 GT/s operation. The device features a non-blocking architecture with low latency cut-through and supports x8, x4, x2, and x1 port configurations. Packaged in a 27mm x 27mm 676-ball FCBGA, it provides multi-root support for up to 12 independent partitions and includes comprehensive reliability features such as SECDED ECC protection on internal RAMs.

Feature Summary

• High-performance non-blocking switch architecture optimized for high throughput and low latency
• Multi-root support enabling dynamic reconfiguration into up to 12 fully independent switch partitions
• Advanced Reliability, Availability, and Serviceability (RAS) including ECRC and end-to-end data path parity protection
• Comprehensive standards compliance including PCI Express Base Specification 3.0 and optional features like AER and ASPM

Applications

• Enterprise servers requiring high-speed inter-domain communication
• Storage arrays and intelligent I/O systems
• Communications infrastructure equipment
• Embedded systems with multiple host requirements

Procurement Notes

Verify the specific ordering suffix YCHLI8 against official Renesas documentation to confirm package type, temperature grade, and lead-free status. Confirm current product lifecycle status as this component family may be subject to discontinuation notices. Ensure compatibility with existing board designs regarding the 676-ball FCBGA footprint and power sequencing requirements before procurement.

Selection Notes

Select this component for applications demanding deterministic switching with minimal latency across multiple peer-to-peer traffic flows. Consider the partitionable architecture if multi-root support or isolated domain communication is required. Verify that the system design accommodates the 676-ball FCBGA package dimensions and thermal dissipation needs associated with high-speed Gen3 signaling.

Part Context

This part belongs to the IDT 89H48H12G3 series of PCIe switches, which was acquired by Renesas Electronics. It serves as a high-density interconnect solution replacing older generation switches in server and storage architectures. The device integrates advanced error reporting and power management features typical of enterprise-grade interface ICs designed for robust system operation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate legacy variants within the 89H48H12G2 series only if backward compatibility with Gen2 specifications is acceptable. Consult official Renesas documentation for any officially designated replacement components.
