89H48T12G2ZDBLG

Overview

The 89H48T12G2ZDBLG is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation. It functions as a PCI Express switch providing 48 lanes and 12 ports for high-performance system interconnect applications. The device utilizes a non-blocking architecture to ensure deterministic throughput across multiple traffic flows. It is housed in a 676-ball FCBGA package with dimensions of 27x27 mm. The component operates at a supply voltage of 3.3V and supports industrial temperature grades. This specific part number represents a lead-free variant within the PES48H12G2 family, designed for low latency and power efficiency in complex switching environments.

Feature Summary

• Provides 48 PCIe Gen2 lanes and 12 switch ports for high-performance system interconnect
• Features a non-blocking switch architecture optimized for maximum bandwidth and large payloads
• Supports partitionable switch architecture for true multi-root support
• Includes internal buffering and flow control credits to optimize throughput regardless of switch loading

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Industrial computing systems requiring deterministic latency

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free certification prior to integration. Check for end-of-life notifications or discontinuation updates from Renesas Electronics. Ensure compatibility with existing PCB footprints and thermal management requirements for the 676-FCBGA package. Validate that the specific suffix matches the required temperature grade and packaging configuration for the target application.

Selection Notes

Select this component when a high-port-count PCIe switch with non-blocking performance is required. Compare against other members of the PES48H12G2 family based on package type, temperature range, and lead-free status. Consider the 676-FCBGA form factor for board space constraints. Evaluate alternative switches if lower lane counts suffice. Verify software tool compatibility, such as the PCI Express Browser, for configuration and testing during the design phase.

Part Context

This part belongs to the IDT/Renesas PES48H12G2 family of PCI Express Gen2 switches. It shares core architectural features with variants like the 89H48H12G2ZCBLGI but differs in package marking and specific suffix designations. The family is known for supporting up to 48 lanes with 12 ports. Related documentation includes datasheets and user manuals for the 89HPES48H12G2 series. Evaluation boards such as the 89KTPES48H12G2 are available for testing functionality.

Replacement Considerations

Publicly confirmed substitute part numbers include 89H48H12G2ZCBLGI and 89H48H12G2ZCBLG. These variants share the same core switching functionality and pinout. Verify package compatibility and temperature specifications before substitution. Consult official Renesas documentation for detailed cross-reference information.
