89H24NT24G2ZCHL

Overview

The Renesas 89H24NT24G2ZCHL is a PCIe Gen2 system interconnect switch providing 24 lanes and 24 ports. It operates with a maximum clock frequency of 125 MHz and supports data rates up to 192 Gb/s. The device utilizes a 324-FCBGA package (19x19 mm) for surface mount installation. Electrical specifications include operating supply voltages of 1 V, 2.5 V, and 3.3 V. The component functions within an industrial temperature range from -40°C to +85°C and features a 32/64-bit data bus width.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture supporting true multi-root configurations
• Supports multiple non-transparent bridging (NTB) functions and movable upstream capabilities

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• I/O expansion systems requiring deterministic latency

Procurement Notes

Verify RoHS compliance status as the specific variant may be marked non-compliant in distributor databases. Confirm current lifecycle status, as this part number is listed as obsolete or end-of-life by major distributors. Ensure compatibility with existing PCB footprints and voltage domains before procurement planning.

Selection Notes

Select this component when 24 independent PCIe Gen2 ports are required for non-blocking traffic flow. Compare against the 89H32 series if higher lane counts are needed. Verify that the 324-FCBGA package dimensions fit the target enclosure constraints. Check for alternative suffixes like ZCHLI8 if lead-free requirements differ from the base model specification.

Part Context

This device belongs to the IDT 89H24NT24G2 family of PCIe switches manufactured by Renesas Electronics. It serves as a direct replacement for legacy IDT interconnect solutions. The part integrates internal buffering and flow control credits to optimize bandwidth utilization for large payloads in enterprise environments.
