Product Description

TI's family of 400 Mb/s physical layer interface chips performs the transceiver functions of initializing the 1394 communications link, arbitrating for access to the channel and actually placing data packets on the media. To meet the different needs of host PCs, hard disk drives, printers and other types of peripheral equipment, the 400 Mb/s devices in the family will offer two, three, four or six 1394 ports.

The product family features several power-saving capabilities, such as a device power-down mode and inactive port disable, that make it well suited to portable and hand-held systems. The family of 400 Mb/s PHY (physical layer) devices also conform to the Device Bay Initiative, an industry effort led by Microsoft, Compaq and Intel which is defining a standard modular design for PC chassis slots for peripheral equipment.

The 400 Mb/s PHY devices will interface directly to TI's 1394 link layer chips, reducing the complexity and cost of systems by eliminating the need for glue logic. As with other 1394 physical layer devices from TI, the 400 Mb/s family will inter-operate with other vendors physical layer devices that conform to the 1394 specification. TI's new PHY device family conforms fully to the latest enhancement to the 1394 specification, the 1394.A version.
