Requirements for laptop and 1394b
As mentioned above, 1394b requires low latency for data transmission (small
receive-FIFO). In order to get the most out of your camera-to-laptop configura-
tion, we recommend the following chipset for your laptop:
• For Intel-based laptops, chipset 915 (or higher)
• For non-Intel based laptops (e.g. AMD), PCI Express compatible chipset
Because most laptops have (only) one PC-card interface, it is possible to con-
nect one PIKE camera to your laptop at full speed. Alternatively laptops with an
additional 1394 ExpressCard interface can be used.
Caution

As mentioned earlier, it is very important not to exceed an
inrush current of 18 mJoule in 3 ms. (This means that a device,
when powered via 12 V bus power must never draw more than
1.5 A, even not in the first 3 ms.)
Higher inrush current may damage the physical interface
chip of the camera and/or the phy chip in your PC.
Whereas inrush current is not a problem for one Pike camera,
daisy chaining multiple cameras or supplying bus power via
(optional) HIROSE power out to circuitry with unknown inrush
currents needs careful design considerations to be on the safe
side.
Note

Recent developments at Apple (TM) allow the INTEL based
Apple computers (both laptops as well as desktops) to run a
Win-OS. This makes it possible to use AVT 1394 camera technol-
ogy with the same AVT SDKs.
