Texas Instruments Rolls Out XIO2213A PCI Express to 1394b Controller

Texas Instruments (TI) (NYSE: TXN) expanded its broad, high-performance 1394 (Firewire[TM]) portfolio with a flexible PCI Express (PCIe) to 1394b open host controller. The packet throughput exceeds 87 MB/s, making the XIO2213A the fastest 1394b controller on the market today. The device’s unique architecture creates a one-chip solution for 1394b for ExpressCards, PC add-in cards and motherboards or docking stations.

Texas Instruments (TI) XIO2213A PCI Express to 1394b ControllerThe XIO2213A provides interoperability by supporting three bilingual 1394 A/B cable ports at 100 Mbps, 200 Mbps, 400 Mbps and 800 Mbps. The device’s internal dedicated PCI bus operates at 32-bit, 66 MHz and includes a pre-fetch agent to optimize PCIe packets for maximum 1394 performance. The translation bridge is fully compliant with the PCI Express Base Specification and supports the standard PCI-to-PCI bridge programming model. Eight 3.3V general-purpose inputs and outputs allow for further system control and customization.

Other key features include the following:

  • 100-MHz differential PCIe common reference clock or 125-MHz single-ended reference clock
  • PCIe adaptive equalization
  • Fully supports provisions of IEEE P1394b-2002
  • Fully compliant with 1394 Open Host Controller Interface Specification
  • Cable power presence monitoring
  • Active state link power management saves power when packet activity on PCIe link is idle
  • 5K asynchronous FIFOs

With the largest 1394b portfolio in the industry, TI makes home networking easy for design engineers, applications providers and consumers. TI’s market-leading 1394b portfolio includes the TSB83AA22C PHY and link layer device, the TSB41BA3B and TSB81BA3D PHY devices. More information on TI’s 1394 portfolio can be found at ti.com/1394.
