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.
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:
- 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.
The XIO2213A is available now in a 167-ball MicroStar 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.
