Product Overview
The PEX8732-CA80BC G is a highly flexible, high-performance 32-lane, 8-port PCI Express (PCIe) Generation 3 packet switch IC engineered by Broadcom Limited. Utilizing the industry-leading PLX Technology ExpressLane switching architecture, this monolithic solution provides multi-host clock domain isolation and multi-point peer-to-peer data transfers at raw signaling speeds up to 8.0 GT/s per lane. The is highly optimized for complex high-availability storage subsystems, cloud computing infrastructures, and high-density industrial server backplanes. It comes fully equipped with programmable Non-Transparent Bridging (NTB) functionality that permits secondary processor mapping patterns, creating isolated redundant host multi-processing networks over a single shared PCIe fabric. Furthermore, on-chip DMA engines offload heavy block data transfers away from host CPUs to optimize overall processing efficiency. Housed in a lead-free, environmentally sustainable FCBGA-676 (27×27mm) package configuration, this switch represents a dependable computing framework for AI acceleration fabrics, medical imaging rigs, and distributed high-speed I/O systems.
Core Advantages
Massive Throughput and Ultra-Low Latency
Maintains an industry-leading standard cut-through package routing latency down to approximately 126 ns while facilitating massive parallel bandwidth delivery across 32 lanes of Gen 3 connectivity.
Flexible Non-Transparent Bridging (NTB)
Enables safe multi-host failover, hardware partitioning, and cross-domain cluster mapping configurations by implementing independent physical window translation arrays without address domain clashing.
Dynamic Lane Bifurcation & Port Allocation
Allows system hardware architectures to dynamically slice the 32 lanes into up to 8 functional ports, ranging from x1 to x8 configurations, easily satisfying unique target board layout arrangements.
Integrated High-Performance DMA Engines
Features embedded dual-host hardware direct memory access (DMA) engines that shift huge memory blocks smoothly across downstream targets, relieving central processing processors from high-volume overhead routines.

Frequently Asked Questions
Q1: Is your current stock inventory of the PEX8732-CA80BC G completely authentic and original?
A: Yes, we guarantee that all PEX8732-CA80BC G switches in our warehouse stock are 100% brand-new, factory-original products from Broadcom, kept and handled under strict anti-static ESD shielding and dry-pack moisture-control guidelines.
Q2: What is the significance of the “G” identifier appended at the end of this Broadcom component code?
A: The “G” suffix indicates a fully lead-free, green packaging configuration, confirming full compliance with international RoHS regulations restricting hazardous substances.
Q3: How does the on-chip visionPAK diagnostic utility assist engineers during system bring-up?
A: visionPAK provides internal diagnostic software utilities that let developers visualize the digital signal eye quality directly on the PCB traces via software registers. This helps pinpoint transmission line reflections and signal attenuation bugs without demanding expensive external oscilloscopes.
Q4: How can our layout team request complete pinout map charts, register reference configuration scripts, or request bulk quotation sheets?
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.
