· Bilingual ports with Screw Holes for thumbscrew locking Type 1394b Cable

Introduction

The FWB-PCIE1X21A combines an OHCI (Open Host Controller Interface) and a high-performance, standards-compliant PCI Express 1.1 host system interface to provide S800 1394b-2002 compliant throughput in a small PCB (Printed Circuit Board) and low power dissipation.

MultipleVCs (Virtual Channels) on the PCI Express link provide native support for QoS (Quality of Service) transmission for real-time and multimedia applications in a standards-based framework, ensuring compatibility with current and future operating systems. Active-state power management allows dynamic power management during periods of reduced network activity.

Technical Specifications
