internally regulated to 1.8 V)
• Serial bus data rates of 100M
bits/s, 200M bits/s, and 400M
bits/s
• Physical write posting of up to
three outstanding transactions
• PCI burst transfers and deep FIFOs to tolerate
large host latency

compatible
90112 IEEE 1394
T
he 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.
