TI Introduces New OHCI 1.1-Compliant IEEE 1394a PHY/Link Control Solutions for the Mobile and Desktop Markets
New Components Offer Lowest Power Consumption in the Industry
DALLAS (July 31, 2001) -- The industry's lowest power IEEE 1394a integrated link controller and physical layer (PHY) devices compatible with version 1.1 of the Open Host Control Interface (OHCI) specification are now available from Texas Instruments Incorporated (TI) (NYSE: TXN). The new devices are the smallest integrated PHY and link controller solutions available, and reduce power consumption up to 67 percent over existing, competing solutions. See www.ti.com/sc/msp6637u.
Mobile 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 new solutions. The TSB43AB21 and TSB43AB23 1394 PHY/Link controllers are the highest performance OHCI solutions available that interface the 1394 high-speed serial bus and the Peripheral Component Interconnect (PCI) bus used in most PCs.
The devices are fully compliant with the latest versions of these standards - PCI Local Bus 2.2, PCI Power Management 1.1 and IEEE 1394a-2000 at 100-, 200- and 400-megabits per second (Mbps), as well as OHCI 1.1, a PC 2001 requirement. The OHCI 1.1 standard 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.
The TSB43AB21 and TSB43AB23 both provide the lowest power consumption available in the industry for mobile PC systems, by implementing an ultra-low power mode that consumes as little as 4.5 milliWatt (mW) during the D3 low power state.
The TSB43AB21 features an integrated 400-megabit per second (Mbps) 1-port PHY, while the TSB43AB23 features a 3-port version. Both devices offer intelligent integrated power management and a 1.8-V core operating voltage with universal PCI interfaces compatible with 3.3-V and 5-V PCI signaling environments. The TSB43AB21 offers pin compatibility with the TSB43AB22, TI's two-port 1394 PHY/link controller solution. Combined with the TSB43AB23, TI offers a flexible line of products and can support designs requiring one-, two-, or three-port solutions.
"These new 1394 devices support the guidelines in Microsoft's Best Practices Design Guide, and will provide designers extensive benefits such as minimizing board space and reducing the bill of materials required," said Randall Trost, Marketing Manager, World Wide Computer Connectivity Solutions.
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, storage devices, DVD players and other equipment requiring easy-to-use high-speed data transmission.
Availability, Pricing, Packaging
The TSB43AB21 and TSB43AB23 1394 PHY/link controller devices are sampling now, with volume production scheduled for third quarter of 2001. Both devices are packaged in a 128-pin lead-free thin quad flatpack (TQFP), with planned pricing of $5.84 each in quantities of 10,000 for the TSB43AB21 and $6.67 in quantities of 10,000 for the TSB43AB23.
