38 Chapter 4: Matrox Rapixo CL Pro hardware reference
In addition to the above video sources, the following video sources are supported
when running in 80-bit configuration:
Matrox Rapixo CL Pro supports power-over-Camera Link (PoCL) and externally
supplied video sources. For compatibility with externally supplied video sources,
Matrox Rapixo CL Pro features SafePower mode to supply power only after
determining whether the connected video source is PoCL compliant. The PoCL
protection on-board fuse can sustain a current of 0.4 A.
Demultiplexers to support time-multiplexed video sources
The acquisition paths of the board feature a demultiplexer. Each can deserialize
input from time-multiplexed video sources on a clock cycle basis.
Time-multiplexed video sources can output larger pixel depths and more taps than
are possible with non-time-multiplexed video sources in the same configuration,
but with a decrease in overall performance. When enabled, the demultiplexer
assumes that two video streams share the same data path and that the streams are
interleaved based on the clock cycle. The demultiplexer assumes that on one clock
cycle, the data is from one stream and that on the next clock cycle, the data is from
another stream. The demultiplexer can only deserialize video inputs that, when
combined and, if necessary, expanded, total a maximum depth of 64 bits per
acquisition path.
Expansion refers to the automatic addition of padding zeros on the most
significant bits (MSB) of 10-, 12-, and 14-bit data to create byte aligned 16-bit
data.
Communication
For each acquisition path, two LVDS pairs are used to transmit and receive
asynchronous serial communication between the video source and the board.
These signals are handled by the Universal Asynchronous Receiver/Transmitters
(UARTs).
For each acquisition path, four camera control output signals are also available.
These are general-purpose signals that are sent to the video source.
