Each acquisition path can grab at a maximum rate of 60 MHz for LVDS and
32 MHz for RS-422. Each acquisition path has its own programmable
synchronization generator (PSG) and LUTs, and can have a different acquisition
rate. Matrox Helios eD/XD supports a comprehensive set of general purpose I/O
and serial ports to control video sources and other devices.
