Linkreal 4 Port Usb3 0 Host Adapter Card

Products Photos Catalog Linkreal Port Usb3 Photos Catalog

LRSU9A72-4A is an 4-port USB3.0 host adapter specifically designed for industrial and vision applications.

USB3.0 or SuperSpeed USB, delivers up to ten times the data rate over USB2.0 and is particularly useful for high-speed data storage and imaging devices.

Most off-the-shelf USB3.0 cards implement multiple ports with a single USB3.0 controller which results in significant performance degradation during multi-port operation.

To achieve maximum per-port performance, PCIe-USB380 has four independent PLX 8608 USB3.0 Host Controllers and x4 PCI Express® Gen2 interface to offer up to 5 Gbps bandwidth for each port, independently.

In addition to transfer data bandwidth advantage, it features on-board regulated 5V DC power supply with a unique configurable 900mA/ 1500mA current limit to supply stable 5V DC power to external USB devices.

It also supports software-programmable per-port power on/ off control for fault recovery operations.

Features • x4 PCI Express® Gen2 interface (2GB/s total bandwidth) • 4-port by 4x NEC/ Renesas μPD720202 host controller • On-board 5V DC regulated power supply, no external power needed • User-configurable 900mA and 1500mA current limit • Software-programmable per-port power on/ off control • Supports cable-lock mechanism for reliable cable connection Parameter Model: LRSU9A72-4A
