FireBoard 800™
technical specifications
1394b PCI OHCI Host Adapter Board
FireBoard 800™
is the first 1394b to PCI OHCI compliant board, which has been designed to meet the demanding requirements of todays 1394 bus designs. FireBoard 800™ is 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.

Design Issues
Logic Design
The entire design of Unibrains FireBoard 800™ is based on
the two main FireWire chip-sets of Texas Instruments:
- TSB81BA3D IEEE-1394b three-port cable TRANSCEIVER/ARBITER
PHY chip.
- 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™ 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.
EMI, EMC testing
FireBoard 800™ 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.
