The FMC DIO 32CH LVDS A uses a VHDCI connector compatible with standard SCSI cables. There is also a micro-HDMI connector on the front panel with I2C and some LVDS signals so that standard HDMI cables can be used. Each channel may be optionally AC-coupled (0R resistors need to be removed) and is ESD-protected. All channels are terminated to 1.65V by two 50 Ohm resistors. The direction of each channel is programmed via a serial, SPI-like interface. The VHDCI connector has also 3.3V supply and buffered I2C interface.
