89H48T12G2ZCBLI

Overview

The 89H48T12G2ZCBLI is a PCIe Gen3 system interconnect switch manufactured by Renesas Electronics. It provides 48 lanes and 12 ports of high-performance, deterministic switching. The device features a non-blocking architecture optimized for high throughput and supports partitionable configurations for multi-root systems. It includes internal buffering and flow control credits to maximize bandwidth efficiency. The component operates within an industrial temperature range and utilizes a 676-lead FCBGA package.

Feature Summary

• Provides 48 PCIe Gen3 lanes across 12 independent switch ports
• Features a non-blocking architecture ensuring full line-rate throughput
• Supports partitionable switch architecture for true multi-root capabilities
• Includes internal buffering and flow control credits for large payload optimization

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Storage area network (SAN) infrastructure
• Enterprise computing platforms requiring deterministic latency

Procurement Notes

Verify the specific suffix ZCBLI against official Renesas documentation to confirm lead count, temperature grade, and RoHS status. Confirm current availability as this product family may be subject to discontinuation notices. Ensure compatibility with existing root complex designs before procurement.

Selection Notes

Select this model when 48 lanes and 12 ports are required for PCIe Gen3 connectivity. Compare against the 89H48H12G2 series if Gen2 performance suffices. Verify that the 676-lead FCBGA footprint matches the target PCB design constraints and thermal management requirements.

Part Context

This part belongs to the IDT PES48H12G2 family of PCIe switches. It serves as a successor or variant to earlier Gen2 models like the 89H48H12G2, offering increased bandwidth per lane while maintaining similar port counts. It is designed for enterprise environments demanding high scalability and low latency.
