Product Overview
The PEX8750-AB80BI G is a premier 48-lane, 12-port PCI Express (PCIe) Generation 3.0 ExpressFabric switch designed by Broadcom (formerly PLX Technology). Engineered to deliver multi-host peer-to-peer data transfers, high scalability, and deterministic ultra-low latency signaling, this specialized IC operates at an impressive throughput rate of 8.0 Gigatransfers per second (GT/s) per lane. Built with proprietary Multi-Host architecture, it allows designers to establish flexible cluster interconnect layouts, failover redundancy parameters, and shared I/O endpoints natively on the hardware plane. Housed in an industrial-grade high-density BGA package, the is highly optimized for modern high-performance computing (HPC) environments, advanced cloud server arrays, big data NVMe storage arrays, and AI-driven acceleration backplanes.
Core Advantages
Ultra-High Dynamic Bandwidth Expansion
Provides a matrix of 48 individual physical PCIe Gen 3 lanes configurable into up to 12 distinct links. This extensive width effortlessly routes multi-gigabit workloads between high-speed CPUs, hardware accelerators, and storage controllers.
Advanced ExpressFabric Architecture
Incorporates integrated hardware non-transparent bridging (NTB) blocks and DMA engines. These enable seamless multi-host sharing of end-point targets while isolating host clock domains to provide strict memory mapping security.
Industry-Leading Low Latency Matrix
Utilizes a highly optimized switch cut-through forwarding topology that reduces total internal packet delay down to approximately 126 nanoseconds, ensuring maximum responsiveness for real-time edge processing nodes and financial trading setups.
Comprehensive Diagnostic Safety
Integrates advanced on-chip performance monitoring tools and visual packet analysis registers (on-chip scope capabilities) that allow system architects to troubleshoot loop parameters and evaluate signal eye tracking without physical scope attachments.

Frequently Asked Questions
Q1: Is your current stock inventory of the PEX8750-AB80BI G completely original and brand new?
A: Yes, we guarantee that all PEX8750-AB80BI G PCIe switches are 100% authentic, factory-fresh components from Broadcom/PLX, stored under moisture-sensitive level (MSL) and anti-static compliance conditions.
Q2: What is the significance of the “G” at the end of the part number string?
A: The “G” suffix indicates Broadcom’s eco-friendly status rating, verifying that the 676-pin package layout complies with lead-free green environmental standards and RoHS certifications.
Q3: What purpose do Non-Transparent Bridges (NTB) serve inside this PCIe switch IC?
A: NTB technology allows two or more distinct CPUs/hosts to connect to the same switch backplane. It maps localized addresses securely, preventing multi-master bus conflicts while facilitating rapid host-to-host mirrored data backup loops.
Q4: How can our engineering desk request specific SDK development software tools or EEPROM programming code tables?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
