Matrox Meteor-II /1394 has three IEEE 1394 input ports to
which 1394 devices can be attached, as long as the configuration
of devices complies with the IEEE 1394 tree topology. Serial
data bus rates of 100, 200, or 400 Mbits per second are shared
across the three ports. MIL-Lite can be used to grab from
monochrome or color IEEE 1394 DCAM-compliant cameras.
Note that YUV 4:2:2 data is grabbed in UYVY format.
The physical layer (PHY) is part of a bi-directional interface
between the link layer (Link) and the actual IEEE 1394 serial
bus. The physical layer acts as a converter, reformatting the
commands and digital data it receives, so that the data can be
transmitted over the serial bus. The PHY monitors the line
conditions to determining connection status, for initialization
and arbitration, and for packet reception and transmission. The
physical layer supports data transmission rates of up to 400
Mbits per second.
