TI Introduces Industry's First OHCI 1.1-Compliant IEEE 1394 PHY/Link Control Solution

New Component Targets Notebooks and Desktop PCs

iOHCILynx Power Consumption

DALLAS (Feb. 20, 2001) -- The industry's first IEEE 1394 integrated link controller and physical layer (PHY) device compatible with version 1.1 of the Open Host Control Interface (OHCI) specification is now available from Texas Instruments Incorporated (TI) (NYSE: TXN). Providing the smallest integrated PHY and link controller solution available, the new component reduces power consumption by 40 percent over existing solutions. See http://www.ti.com/sc/msp5762u.

The TSB43AB22 1394 PHY/Link Controller offers the highest performance among available OHCI solutions that interface the 1394 high-speed serial bus and the Peripheral Component Interconnect (PCI) bus used in most PCs. The device is fully compliant with the latest versions of these standards - PCI Bus 2.2, PCI Power Management 1.1 and IEEE 1394a-2000 at 100-, 200- and 400-megabits per second (Mbps). Notebook and desktop PCs, PCI add-in cards and PC cards will benefit from the low power consumption, small footprint, cost efficiency and higher performance of the TSB43AB22.

The TSB43AB22 provides the lowest power consumption in the industry for mobile PC systems, consuming less than one milliWatt (mW) during the D3 low power state. The device features an integrated 400-megabit per second (Mbps) two port PHY, intelligent integrated power management, a 1.8-V core operating voltage and pin-compatibility with the TSB43AA22, TI's earlier-generation iOHCI-Lynx 1394 PHY/link controller solution. These features save system manufacturers board space, cost and development time in the introduction of new mobile PC products. In addition, deep first-in first-out (FIFO) memories capable of handling the maximum sized asynchronous and isochronous packets provide greater tolerance for PCI bus latency, improving system performance.

"We chose TI's TSB43AB22 for our new notebook products so we could offer our customers the enhanced multimedia and connectivity that 1394 provides, as well as meet PC 2001 guidelines for new OHCI 1.1 features," said Lorena Kubera, director of mobile product marketing, Compaq Computer Corporation. "The device's low power consumption extends battery life and enhances portability in next-generation high-performance systems."

The IEEE 1394 high-speed serial interface is widely used in many products including personal computers, consumer electronics and PC peripherals, allowing PCs to connect to camcorders, DVD players, TVs and other equipment requiring easy-to-use high-speed data transmission. The OHCI 1.1 standard for the 1394 interface provides for the implementation of features supporting greater asynchronous and isochronous transmission of data, as well as more advanced power management over earlier versions of the standard.

TI has been a leader in supplying IEEE 1394 solutions before the original version of the standard was released in 1995. TI's latest announced PHY/link controller augments a diverse line of 1394 products in lead-free package options.

Availability, Pricing, Packaging

The TSB43AB22 1394 PHY/link controller device is sampling now, with volume production planned for March 2001. The TSB43AB22 is packaged in a 128-lead thin quad flatpack (TQFP), with planned pricing of $6.49 each in quantities of 10,000.
