32(only 400mbp's) or 64-bit compatible(true full 800mbp's), with 64-bit burst speeds up to 266MB/s

The powerful Texas Instruments FireWire 800 controller chip

FireCard800" is the first 1394b to PCI OHCI compliant board, which has been designed to meet the demanding requirements of today's 1394 bus designs. FireBoard800" is a 64bit PCI OHCI Host Adapter capable of exceptional 800Mbit/sec performance, providing the throughput and bandwidth to move data efficiently and quickly between the PCI and 1394 busses. This board also provides outstanding ultra-low power operation and intelligent power management capabilities, being compliant with all the latest 1394, OHCI and PCI specification/standards.

FireCard800" operates as the interface between a selectable 64-bit 33-MHz or 32-bit 33-MHz PCI Local Bus and a compatible 1394b bus. Its PHY-layer device is capable supporting serial data rates of s400 and s800
