PCI CARD

High-Speed Serial

Device

The SMART 90112 IEEE1394 high speed serial device is a PCI-to-1394 interface card compliant with the PCI Local Bus Specification, PCI Bus Power Management Interface Specification, IEEE Std 1394-1995, and 1394 Open Host

Controller Interface Specification. The controller used, the TI TSB12LV26 controller, provides the IEEE 1394 link function and is compatible with 100M bits/s, 200M bits/s, and 400M bits/s serial bus data rates.

As required by the 1394 Open Host Controller Interface Specification (OHCI) and IEEE Std 1394a-2000, internal control registers are memory-mapped and nonprefetchable. The PCI configuration header is accessed through configuration cycles specified by PCI and provides plug-and-play (PnP) compatibility. Furthermore, the SMART 1394 card is compliant with the PCI Bus Power Management Interface Specification, per the PC 99 Design Guide requirements. The SMART 1394 card supports the D0, D2, and D3 power states.

The design provides PCI bus master bursting and is capable of transferring a cacheline of data at 132M bytes/s after connection to the memory controller. Since PCI latency can be large, deep FIFOs are provided to buffer 1394 data.

The TSB12LV26 device provides physical write posting buffers and a highly-tuned physical data path for SBP-2 performance. The TSB12LV26 device also provides multiple isochronous contexts, multiple cacheline burst transfers, advanced internal arbitration, and bus-holding buffers on the PHY/link interface.

An advanced CMOS process achieves low power consumption and allows the SMART 1394 card to operate at PCI clock rates up to 33 MHz.
