89H48H12AG2ZCBLGI

Overview

The 89H48H12AG2ZCBLGI is a specialized integrated circuit interface component 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 full line-rate throughput across multiple traffic flows regardless of switch loading. It operates with a 3.3V supply voltage and is housed in a 676-FCBGA package measuring 27x27 mm. The component supports surface mount installation and complies with RoHS3 standards.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Partitionable switch architecture supporting true multi-root configurations
• Internal buffering and flow control credits optimized for maximum bandwidth and large payloads

Applications

• High-performance system interconnect switching
• Multi-root support environments
• PCIe expansion systems requiring deterministic latency

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or alternative packaging types such as tape and reel variants. Confirm the specific suffix ZCBLGI matches the required lead-free and industrial temperature grade specifications before procurement.

Selection Notes

Select this part for designs requiring a 12-port, 48-lane PCIe Gen2 switch with non-blocking performance. Ensure the PCB layout accommodates the 676-ball FCBGA footprint with a 27x27 mm dimension. Verify that the system power supply provides stable 3.3V rails and that the host root complex supports the required PCIe topology for partitionable switch operation.

Part Context

This part belongs to the PES48H12G2 family of PCIe switches from Renesas (formerly IDT). It shares architectural similarities with other models like the 89H48H12G2 but differs in package type and specific suffix designations indicating manufacturing attributes. It serves as a core interconnect solution for servers and storage systems needing high-bandwidth connectivity.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, engineers must evaluate newer generations of PCIe switches from Renesas or other vendors that offer equivalent port counts and lane densities while ensuring pin-to-pin compatibility or redesigning the interface logic.
