89H48T12G2ZCBLI8

Overview

The 89H48T12G2ZCBLI8 is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 48 lanes and 12 ports with non-blocking architecture for high-performance data transfer. The device operates at a maximum clock frequency of 125 MHz, supporting a total data rate of 96 Gb/s. It utilizes a 32/64-bit data bus width and functions within a voltage range of 1 V to 3.3 V. The component is housed in a 676-FCBGA package (27x27 mm) and supports surface mount installation. It is rated for industrial temperature grades, operating between -40°C and +85°C.

Feature Summary

• Non-blocking switch architecture optimized for deterministic system interconnect switching
• Partitionable switch design enabling true multi-root support capabilities
• Internal buffering and flow control credits optimized for large payloads

Applications

• High-performance server system interconnects
• Storage area network (SAN) infrastructure
• Enterprise computing platforms requiring multi-root topology

Procurement Notes

This specific part number is listed as obsolete or end-of-life across major distributors. Verification of availability requires checking secondary market suppliers or confirming if alternative packaging suffixes are currently active. Ensure the RoHS status matches project requirements, as older batches may differ from current compliance standards.

Selection Notes

Select this component when designing systems requiring 48 PCIe Gen2 lanes with low latency. Verify that the host platform supports the required 1V, 2.5V, and 3.3V power rails. Confirm PCB layout compatibility with the 676-FCBGA footprint and ensure thermal management solutions accommodate the package density.

Part Context

This model belongs to the 89H48 series of PCIe switches, designed for high-bandwidth applications. It shares architectural similarities with the 89H12NT12G2 but offers significantly higher port density. The 'ZCBLI8' suffix indicates specific packaging, temperature grade, and lead-free composition details defined by the manufacturer's coding system.

Replacement Considerations

Direct substitutes include other variants within the 89H48H12G2 family, such as 89H48H12G2ZCBLGI8, which may offer different RoHS compliance or packaging options. Evaluate pin-to-pin compatibility and software configuration tools before transitioning.
