89H48T12G2ZCBLG8

Overview

The 89H48T12G2ZCBLG8 is a PCIe Gen2 system interconnect switch providing 48 lanes and 12 ports. It features a non-blocking architecture optimized for high-performance applications, supporting partitionable configurations for multi-root systems. The device utilizes internal buffering and flow control credits to maximize bandwidth and handle large payloads with low latency. It operates within a commercial temperature range of 0°C to +70°C and is housed in a 676-FCBGA package measuring 27x27 mm. This specific suffix indicates a reel packaging format.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput for multiple traffic flows regardless of switch loading.
• Partitionable switch design enabling true multi-root support for flexible system configurations.
• Internal buffering and flow control credits optimized for maximum bandwidth and large payload handling.

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Storage area networks

Procurement Notes

Verify the component status as obsolete or end-of-life through official Renesas channels before procurement planning. Confirm that the '8' suffix strictly denotes the reel packaging type and does not alter electrical functionality. Ensure compatibility with existing board designs given the discontinued status of this specific part number.

Selection Notes

Select this component when a 48-lane, 12-port PCIe Gen2 switch is required for deterministic system interconnects. Consider the 676-FCBGA footprint constraints during PCB layout. Evaluate alternative packages such as tray versions if reel availability is restricted, noting that functional specifications remain consistent across packaging variants.

Part Context

This part belongs to the 89H48H12G2 family of PCIe switches. Variants differ primarily by temperature grade (Commercial vs Industrial) and packaging (Tray vs Reel). The ZCBLG8 designation specifies the Commercial grade, lead-free composition, and reel packaging format within this product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the product is listed as obsolete, consult Renesas Electronics for current recommended replacements or lifecycle notifications.
