FireBoard800™
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.
FireBoard800™
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.

Logic
Design - The entire design of Unibrain's FireBoard800™
is based on two main FireWire Chipsets:
- the Texas Instruments TSB81BA3
IEEE-1394b three-port cable
TRANSCEIVER/ARBITER
- the Texas Instruments TSB82AA2
IEEE-1394b OHCI-Lynx Controller
Moreover,
special importance has been considered in the usage of:
- Low Jitter External Crystal
Oscillator at 98.304 MHz
- Separate Bias (TPBIAS) for Each
Port
PCB Design
- The FireBoard800™ card is a four-layer printed circuit
PCI board. Two of the layers provide the signal interconnections
(signal layers) while the remaining two layers provide the required
power and ground interconnections (plane layers). Special consideration
has been taken for the TPA, TPB signals routing in order to
have the same length per port. Also, land patterns with ground
have been used to isolate critical signals from the noisy environment.
