Product Overview
The PEX8724-CA80BC G is a low-latency 24-lane 6-port PCIe Gen3 switch from Broadcom (ex PLX). Running at 8.0 GT/s per lane, it adopts ExpressLane multi-host architecture to support host failover and high-speed DMA transmission. Compatible backward with PCIe Gen1/Gen2, this lead-free 324-ball HFCBGA chip suits cloud servers, storage controllers, accelerators and high-performance embedded hardware.
Core Advantages
Flexible Lane Bifurcation
Configurable port bifurcation, split 24 PCIe Gen3 lanes into up to 6 ports with x1/x2/x4/x8 width options.
Multi-Host & Non-Transparent Bridging (NTB)
Dual-host design with NTB function, enables multi-CPU clusters to share resources with isolation and backup redundancy.
DMA Engine Integration
Built-in DMA controller per port, realizing fast endpoint data transmission without occupying host CPU resources.
Power-Efficient, Compact Package
40nm process + 19×19mm HFCBGA packaging, great heat dissipation and small footprint for dense PCB layout.

Frequently Asked Questions
Q1: What does “G” suffix in PEX8724-CA80BC G mean?
A1: “G” stands for green environmental grade. This chip is lead-free, halogen-free and fully RoHS compliant with eco-friendly solder materials.
Q2: Is PEX8724-CA80BC G compatible with PCIe Gen1/Gen2?
A2: Yes. It auto-negotiates 2.5GT/s or 5.0GT/s for older PCIe devices without firmware changes.
Q3: What is Non-Transparent Bridging (NTB)?
A3: NTB isolates two host processors, allowing secure data exchange between multi-CPU clusters without full RAM access, ideal for failover server systems.
Q4: How to cool this BGA chip for long operation?
A4: Use high thermal conductivity thermal pad, add PCB thermal vias under BGA pads, or install passive heat sinks. Contact us for thermal layout files.
Q5: What is the minimum order quantity for this part?
A5: Standard tray packaging is 84 pcs. Small sample orders are available upon request.
Q6: Does this PCIe switch support lane bifurcation?
A6: Yes. Its 24 lanes can be split into up to 6 ports in x1/x2/x4/x8 combinations for flexible hardware layout.
Q7: What’s the operating temperature range of PEX8724-CA80BC G?
A7: Commercial grade range 0°C ~ +70°C, suitable for server and embedded industrial equipment.
Q8: Can you provide PCB footprint and IBIS simulation files?
A8: Sure, send us an inquiry and we will share complete CAD design documents free of charge.
