Original Press Release:

TI Introduces Industry's Highest Performance PCI Express to 1394b Controller

Broadest 1394 portfolio enables real-time data applications

DALLAS (April 10, 2008) - Texas Instruments (TI) today 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. (See

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

The XIO2213A is available now in a 167-ball MicroStar(TM) BGA package. Suggested resale pricing in 1000-unit quantities is $8.70. Evaluation modules are available online. Additionally, TI has partnered with Unibrain to provide complementary 1394b drivers for TI's 1394b customers.
