Introduction

The FWB-PCIE1X20 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

PCI Express:
  • Designed for compliance with PCI Express.
  • Multiple virtual channel (VC0,VC1 ) support fordiffe-rentiating 1394 isochronous traffic.
  • Supports eight user-programmable traffic classes.
  • 64-bit and 32-bit platform support.
  • Interrupts via legacy INTx interface or message sig-naled interrupt (MSI).
  • Supports PCI Express clock power management viaCLKREQN signal for form factors that support thisprotocol.
  • Supports all linkpowermanagement states (L0,L0s,L1,andL2/L3) and active state power management(ASPM).
  • Supports wake-up from a low-power state via in-bandbeacon signaling and side-band WAKE_N signal.
OHCI (Open Host Controller Interface)
  • Enhanced with the OHCI 1.2 draft specification for 1394b-2002 PHY full operational compliance.
  • OHCI 1.0 backwards compatible. Configurable via EEPROM to operate in either OHCI 1.0 or OHCI 1.1 mode.
  • 8 Kbyte isochronous transmit FIFO.
  • 4 Kbyte asynchronous transmit FIFO.
  • 8 Kbyte isochronous receive FIFO.
  • 8 Kbyte asynchronous receive FIFO.
  • Dedicated asynchronous and isochronous descriptor-based DMA engines.
  • Eight isochronous transmit contexts.
  • Eight isochronous receive contexts.
  • Supports parallel processing of incoming physical read and write requests.
  • Supports up to 48-bit addressing per OHCI specifica-tion for the physical DMA transfers.
1394b-2002 Link
  • Cycle master and isochronous resource manager capable.
  • Supports 1394a-2000 and 1394b-2002 acceleration features.
1394b-2002 PHY
  • Provides three IEEER 1394b-2002 compliant ports sup-porting 1394b-2002 speeds of 800 Mbits/s and 400Mbits/s while maintaining backward compatibility to IEEE 1394a-2000 speeds of 100 Mbits/s, 200Mbits/s, and 400 Mbits/s over 4.5 m copper.
  • Fully supports provisions of IEEE 1394a-2000 and 1394-1995 standards for high-performance serial bus.
  • Link is not required for hub operation.
  • Supports extended BIAS_HANDSHAKE time for enhanced interoperability with camcorders.
  • Does not require external filter capacitor for PLL.
  • Supports arbitrated short bus reset to improve utiliza-tion of the bus.
  • Supports ack-accelerated arbitration and fly-by concat-enation.
  • Supports PHY pinging and remote PHY access pack-ets.
  • Fully supports suspend/resume.
