89H48H12G3YCHLGI8

Overview

The 89H48H12G3YCHLGI8 is a PCI Express Gen3 system interconnect switch manufactured by Renesas Electronics. It provides 48 PCIe Gen3 lanes and 12 switch ports, delivering non-blocking throughput for high-performance applications. The device operates with supply voltages of 1 V, 2.5 V, and 3.3 V, supporting data rates up to 8 Gt/s per lane. It features an industrial temperature range from -40°C to +85°C and is housed in a 676-ball FCBGA package measuring 27x27 mm.

Feature Summary

• Supports 48 PCIe Gen3 lanes across 12 ports for deterministic system interconnect switching
• Non-blocking architecture ensures full line-rate throughput regardless of switch loading
• Partitionable switch design enables true multi-root support for flexible system configurations

Applications

• High-performance computing server backplanes
• Storage area network (SAN) infrastructure
• Industrial automation control systems

Procurement Notes

Verify the specific suffix YCHLGI8 against official Renesas documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for end-of-life notifications or obsolescence warnings as this component family may have discontinued variants.

Selection Notes

Select this model when 48 lanes of PCIe Gen3 connectivity are required within a single switch IC. Ensure the PCB layout supports the 676-ball FCBGA package dimensions. Verify that the power delivery network can handle the combined current requirements for 1 V, 2.5 V, and 3.3 V rails simultaneously.

Part Context

This part belongs to the IDT 89HPES48H12 series, which was acquired by Renesas Electronics. It serves as a successor to earlier Gen2 switches like the 89H48H12G2, offering higher bandwidth capabilities while maintaining similar port counts and architectural flexibility for enterprise and industrial markets.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific variant are not available in the provided documentation. Users should consult Renesas technical support for direct replacements or evaluate the broader 89HPES48H12 family for compatible alternatives.
