The MDK-MB is fully compatible with MityDSP and MityDSP-XM processor cards with Bank 7 configured in LVDS mode. The MDK-MB includes on board RS-232, 10/100 MBit Ethernet and Universal Serial Bus (USB) communications interfaces. For basic data acquisition and control, an 8 channel 12-bit DAC and an 8 channel 12-bit ADC is included. For display, an LVDS link connection to an off-board quarter VGA (QGVA) display controller with backlight driver is provided. 1 Copyright 2007-20013, Critical Link LLC Critical Link, LLC MDK-MB Rev-B www.CriticalLink.com MityDSP Development Kit Mother Board www.MityDSP.com 28 March 2013 In addition to the on-board I/O interfaces, the MDK-MB provides interfaces for four MityDSP Development Kit (MDK) MDK-8 and four MDK-4 form factor daughter card sites for system expansion. The daughter card sites are laid-out to also allow the use of MDK-12, MDK-16, and MDK-24 size daughter cards by combining card slots as described in the Daughter Card Configuration section, below. The MDK daughter cards allow customization of the system card based on the application. Users may select from several off-the-shelf cards available from Critical Link or design their own based on their specific requirements. The MDK-Pro-MB includes on board voltage regulation for providing power digital and analog circuits. The card requires a power supply capable of providing a nominal +9 to +18 Volts DC. Input power can be supplied via the 2-pin 0.156 Molex header, or a standard barrel-style power jack. A block diagram of the MDK-MB is illustrated in Figure 1. All available FPGA I/O lines and the two 6711 McBSP ports are either used directly by the MDK-MB or are routed to the MDK daughter card sites. Control of the on-board interface hardware and connected daughter cards require proper configuration of the MityDSP FPGA and DSP. While not required, it is strongly recommended that the MityDSP software and firmware development kit and supplied API be used to manage these interfaces. 2 Copyright 2007-20013, Critical Link LLC
