FireBoard800 GOF-LC™
technical specifications
1394b PCI OHCI Host Adapter Board
FireBoard 800 GOF-LC™
is the first 1394b to PCI OHCI compliant board, which has been
designed to meet the demanding requirements of today’s 1394 bus
designs. FireBoard 800 GOF-LC™ is capable of exceptional 800Mbit/sec
performance, providing the throughput and bandwidth to move data
efficiently and quickly between the PCI and 1394 busses. Through the Glass
Optical Fiber (GOF) port type LC, the S800 (800Mbps) transmission of 1394b bus
extends up to 550 meters distance.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.

Logic Design
The entire design of
Unibrain’s FireBoard 800 GOF-LC™ is based on the two main
FireWire chip-sets of Texas Instruments:
- TSB81BA3 IEEE-1394b three-port cable
TRANSCEIVER/ARBITER
- 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 FireBoard 800 GOF-LC™ 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.
Operating Voltage
12V DC - CAUTION: additional power
supply voltage on the Firewire bus should be equal to 12V
Operating Free-air Temperature
0°C to 70 °C
Humidity
10% to 90% non condensing.
FCC / CE Compatibility and EMI, EMC testing
FireBoard 800 GOF-LC™ has successfully
passed the EN 55022 (Emissions Environment) and EN 55024
(Immunity Environment) EMI test procedures.
Subsequently, this product is fully CE compliant and
assigned with the CE mark. The board is also FCC
compliant.
