89H48T12G2ZDBL

Overview

The 89H48T12G2ZDBL is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, functioning as a PCI Express system interconnect switch. This component provides 48 PCIe Gen2 lanes and supports 12 switch ports, delivering high-performance, deterministic switching capabilities for complex system architectures. It features a non-blocking switch architecture optimized for high-speed data throughput and includes internal buffering with flow control credits to manage large payloads efficiently. Designed for surface mount installation, the device utilizes a 676-ball FCBGA package (27x27 mm) to facilitate dense PCB layouts in demanding industrial or server environments.

Feature Summary

• Non-blocking switch architecture ensuring full line-rate throughput across all ports regardless of traffic load
• Partitionable switch design enabling true multi-root support for flexible system configurations
• Internal buffering and flow control mechanisms optimized for maximum bandwidth utilization

Applications

• High-performance system interconnect switching
• Multi-root server architectures requiring deterministic latency
• Industrial automation systems needing robust PCIe connectivity

Procurement Notes

Verify current availability status directly with authorized distributors or the manufacturer, as this specific part number may be subject to discontinuation or limited stock constraints. Confirm RoHS compliance and lead times prior to procurement planning. Ensure compatibility with existing board designs regarding the 676-FCBGA footprint and voltage requirements before finalizing orders.

Selection Notes

Select this component when designing systems that require a partitionable PCIe switch with 48 lanes and 12 ports. Ensure the application demands non-blocking performance and low latency typical of Gen2 specifications. Verify that the host platform supports the required power rails and thermal dissipation for the FCBGA package. Consider alternative models if higher generation speeds or different port counts are needed.

Part Context

This part belongs to the 89H48 series of PCIe switches from Renesas, designed for high-density interconnect solutions. It shares architectural similarities with other members like the 89H48H12G2 but differs in specific packaging and commercial variants. The series is engineered for enterprise and industrial applications requiring reliable, high-bandwidth data routing between multiple PCIe endpoints.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific variant are not available in verified documentation. Engineers should consult official Renesas resources for potential obsolescence management strategies or equivalent products within the same family.
