Product Overview

The PEX8718-AB80BI G is a high-performance 16-lane, 5-port PCI Express (PCIe) Generation 3 switch matrix designed by Broadcom Limited. Architected with PLX Technology ExpressLane switching logic, this silicon device supports multi-channel peer-to-peer data transmission with a maximum throughput speed of 8.0 GT/s per lane. The PEX8718-AB80BI G supports Non-Transparent Bridging (NTB) multi-host configurations, delivering hardware isolation and failover backup links for enterprise storage controllers and industrial networking backplanes. It integrates optimized direct memory access (DMA) hardware engines to reduce CPU load and cut end-to-end signal latency. Packaged in reliable lead-free FCBGA-324 (19×19mm), this PCIe Gen 3 switch is suitable for edge AI accelerators, rugged industrial servers and multi-channel vision processing systems.

Core Advantages

Ultra-Low Packet Latency Matrix

Delivers cut-through latency down to approximately 126 ns (reference value from same ExpressLane Gen3 product line), eliminating transmission bottlenecks under heavy multi-point peer data routing workloads.

Advanced Multi-Host and Non-Transparent Bridging (NTB)

Built-in NTB function supports multi-processor isolated computing networks, enabling secure cross-host data transmission over shared PCIe buses without memory address conflicts.

Flexible Lane Bifurcation and Port Splitting

Configurable physical port allocation across its 16 Gen3 lanes; designers can set each downlink port from x1 to x8 width to match different peripheral hardware layouts.

Integrated On-Chip DMA Sub-Engine

Embedded dedicated DMA channels accelerate large memory block data transfer, offloading data movement tasks from host processors to release system compute resources.

Frequently Asked Questions

Q1: Is your PEX8718-AB80BI G fully original Broadcom factory stock?

A: All PEX8718-AB80BI G switches in our warehouse are brand-new genuine Broadcom components, stored and shipped with complete ESD anti-static and moisture-proof dry-pack packaging protection.

Q2: What does the suffix “G” at the end of part number represent?

A: The “G” suffix stands for Green halogen-free lead-free packaging, fully compliant with RoHS 10 environmental hazardous substance restrictions.

Q3: How does NTB function realize dual-host system redundant backup?

A: NTB hardware isolates independent memory address spaces for two connected host processors. It builds isolated high-speed data transmission channels, preventing fault on one host from causing memory corruption of the backup host.

Q4: How can I obtain pinout tables, register configuration docs and bulk tier pricing?

A: Fill out the quick inquiry form on this page with your project demand details. Our technical support will send full datasheet and related engineering documents within 24 working hours.
