89H22H16G2ZCBLG

Overview

The Renesas Electronics 89H22H16G2ZCBLG is a PCI Express Gen2 switch interface IC designed for high-performance system interconnect applications. It provides 22 lanes and 16 ports of non-blocking switching capability, supporting a maximum clock frequency of 125 MHz with a data rate of 176 Gb/s. The device operates within a temperature range of 0°C to +70°C and utilizes multiple power supply voltages including 1 V, 2.5 V, and 3.3 V. It is housed in an FCBGA-1156 surface-mount package and is classified as obsolete.

Feature Summary

• Features non-blocking architecture optimized for high performance and full line-rate throughput
• Supports partitionable switch architecture for multi-root configurations

Applications

• High-performance system interconnect switching
• Multi-root support architectures
• PCIe Gen2 network infrastructure

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted to existing stock or secondary market sources. Verify RoHS compliance status and moisture sensitivity level (MSL) requirements before procurement, as handling precautions may apply due to its age and packaging specifications.

Selection Notes

Engineers should consider this part only for maintenance of legacy designs requiring 22 lanes and 16 ports. New designs are advised to evaluate current-generation PCIe switches from Renesas or other vendors, as this specific model no longer receives manufacturing support or standard distribution channels.

Part Context

The 89H22H16G2ZCBLG belongs to the IDT/Renesas 89HPES series of PCIe Gen2 switches. It shares architectural similarities with the 89H64H16G2 but offers a reduced lane count of 22 compared to higher-end models. The suffix ZCBLG indicates lead-free composition and specific packaging configuration within the FCBGA family.

Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Designers must perform functional equivalence analysis when selecting alternative PCIe Gen2 switches with comparable port counts and lane densities.
