Product Overview
The USB3382-AB50NI G PCIe Gen2 to USB3.0 bridge was originally developed by PLX Technology and now belongs to Broadcom after Avago’s acquisition. This single-chip device carries full-rate high-bandwidth data transfer via dual independent PCIe Gen2 x1 upstream ports and one USB3.0 downstream port with internal crossbar forwarding. Built-in multi-domain power management cuts idle power consumption for embedded and industrial devices. Housed in a compact 10 mm × 10 mm QFN-136 package with link training and loopback circuits, it fits SBC expansion cards, video capture gear, medical data acquisition equipment and compact storage adapters.
Core Advantages
Dual Independent PCIe Gen2 Upstream Ports
Two separate PCIe x1 Gen2 interfaces connect to host boards via internal high-speed crossbar switch, supporting parallel data transmission without bandwidth bottlenecks for multi-host expansion equipment.
Integrated Low-Latency PCIe & USB PHYs
On-die physical layer transceivers eliminate external discrete PHY chips, reducing BOM count, simplifying high-frequency PCB routing and lowering multi-layer board manufacturing cost.
Low Operational & Active Standby Power Profiles
Hardware power gating disables unused circuit blocks dynamically, meeting energy efficiency standards and minimizing thermal load for fanless sealed small-form-factor devices.
4 Independent Scatter-Gather DMA Engines
Built-in programmable DMA channels offload bulk packet processing from host CPU, drastically reducing system latency and freeing main processor resources for core application tasks.

Frequently Asked Questions
Q1: Is your currently available stock of the USB3382-AB50NI G controller 100% genuine and original?
A: Yes, we guarantee that all USB3382-AB50NI G components in our warehouse are 100% brand-new, factory-original products sourced from Broadcom legacy stock. Every batch is packed in vacuum-sealed Moisture Barrier Bags (MBB) with full ESD protection to preserve solderability and chip integrity.
Q2: What is the primary benefit of the unique “QFN” package configuration used on the USB3382?
A: The QFN (Advanced Quad Flat No-Lead) package combines low profile, low parasitic inductance and excellent thermal dissipation. Its staggered multi-row pin layout supports high pin count while simplifying high-speed PCB escape routing, cutting multi-layer PCB cost compared to micro-BGA alternatives.
Q3: Does this bridging chip require specialized driver installation to operate under modern operating systems?
A: The USB3382-AB50NI G complies with standard PCIe and USB protocol specifications. Standard use cases like mass storage and generic communication work with native built-in drivers for Windows, Linux and mainstream RTOS. Custom proprietary hardware functions can be developed with official Broadcom SDK packages.
Q4: How can our physical engineering group get formal component engineering drawings, firmware binary packages, or request bulk wholesale pricing tiers?
A: Please complete the Quick Inquiry form on this webpage with your target purchase quantities. Our application support team will deliver complete technical documentation and tiered bulk pricing within 24 hours.
