89H48H12G2ZCBLGI8

Overview

The 89H48H12G2ZCBLGI8 is a PCI Express Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 48 PCIe lanes across 12 ports, delivering non-blocking throughput for high-performance applications. The device operates within an industrial temperature range of -40°C to +85°C and utilizes a 324-FCBGA package with dimensions of 19x19 mm. Power requirements include supply voltages of 1 V, 2.5 V, and 3.3 V. The component supports data rates up to 96 Gb/s and features a 32/64-bit data bus width. It is classified as obsolete status.

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 for maximum bandwidth

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Industrial computing environments

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current lifecycle status and end-of-life notifications is required before integration into new designs. Sourcing should focus on authorized channels or approved surplus markets to ensure authenticity.

Selection Notes

Engineers selecting this part must account for its discontinued status and limited future availability. The 324-FCBGA footprint requires specific PCB layout considerations for thermal management and signal integrity. Designers should evaluate alternative newer generation switches if long-term production support is a critical requirement for the target application.

Part Context

The 89H48H12G2ZCBLGI8 belongs to the IDT 89H series of PCIe switches, specifically designed for Gen2 speeds. It shares architectural similarities with other models like the 89H12NT12G2 but offers higher port density. The 'ZCBLGI8' suffix indicates specific packaging, lead-free composition, and industrial temperature grading distinct from commercial variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements are not explicitly listed. Engineers should consult Renesas for current portfolio recommendations or perform full electrical and mechanical compatibility analysis for potential alternatives.
