Introduction

The FWBX3-PCIE1XE120 is a Triple OHCI FireWire 800 (IEEE 1394b) to PCI Express Host Adapter.

FWBX3-PCIE1XE120 is designed with two key components.

  • 4-Lane, 4-Port PCI Express Switch.
  • OHCI 1.2 Compliant IEEE 1394b Single Chip Host Controller.

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.
