89H22H16G2ZCBLI

Overview

The 89H22H16G2ZCBLI is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 22 lanes and 16 ports for high-performance, deterministic switching. The device supports a maximum clock frequency of 125 MHz with a data rate of 176 Gb/s. It operates within a commercial temperature range of 0°C to +70°C and utilizes an FCBGA-1156 package. Power supplies include 1 V, 2.5 V, and 3.3 V rails. This component is classified as End-of-Life (EOL) and is no longer in active production.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support capabilities
• Internal buffering and flow control credits designed for maximum bandwidth and large payload handling

Applications

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

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Availability is restricted to remaining stock from authorized distributors or secondary market sources. Buyers must verify lot dates and physical condition carefully. No new units are produced. Compliance with RoHS directives should be confirmed via specific datasheet documentation for this suffix variant.

Selection Notes

Engineers replacing this part must account for its EOL status. Design modifications may be necessary to accommodate newer generation switches or alternative pin-compatible devices if available. Verify that the target application does not require industrial temperature ranges (-40°C to +85°C), as this specific model is rated for commercial temperatures only. Ensure power delivery networks support the required 1V, 2.5V, and 3.3V levels.

Part Context

The 89H22H16G2ZCBLI belongs to the IDT/Renesas 89H series of PCIe Gen2 switches. It sits between smaller 12-lane models and larger 48-lane variants in the product family. The 'Z' indicates lead-free composition, 'C' denotes commercial temperature grade, 'B' specifies the FCBGA package type, 'L' refers to the lead count/pitch, and 'I' indicates the industrial temperature grade suffix conflict which requires datasheet verification against the 'C' commercial rating listed in primary specs.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the EOL status. Potential alternatives include the 89HPES22H16 series or newer PCIe Gen3/Gen4 switches from Renesas, though these require significant design changes. Consult the official replacement guide for cross-reference options.
