MityDSP Development Kit Mother Board

DAC Description
The MDK-MB provides an on-board 8 channel 12-bit digital to analog converter to the
MityDSP TI DSP via McBSP port 2. The DAC part is the TLV5610 from Texas
Instruments / Burr Brown and is capable of output settling times of 2 usec.
All output channels are buffered and provide an output impedance of less than TBD
ohms. All eight channels are routed to the external DAC connector and provide a voltage
output range of 0 to 10 Volts.
Four of eight channels are also independently buffered and routed (1 each) to the 4
MDK-8 daughter card slots and provide an output range of 0 to 4.096 Volts. Note:
These 4 DAC outputs are effectively shared between the MDK-8 daughter card slots and
the external connector. Use of an MDK-8 (or larger form factor cards in an MDK-8 slot)
cards that require the use an associated DAC line implies that the corresponding pin on
the external DAC connector should not be used. Please refer to the data sheet for a
specific daughter card in order to determine if the DAC slot is required.
For details regarding the signal interface to the MityDSP McBSP port, please refer to the
MDK-MB reference schematic. The MityDSP software development kit includes an API
for interfacing to the TLV5610.
Real Time Clock Description
The MDK-MB provides a real-time clock using an I2C device with part number
M41T81SM6F. Use of the RTC requires an implementation of an I2C driver interface
within the FPGA of the MityDSP. The MityDSP software development kit includes an
API for interfacing to the M41T81SM6F.
For details regarding the signal interface to the MityDSP I/O pins, please refer to the
MDK-MB reference schematic.
LVDS Interface Description
The MDK-MB provides a flat-ribbon cable low profile interface for five Low Voltage
Differential Signaling (LVDS) pairs
The interface design is intended to support high
.
speed off board interconnects. In addition to custom user interfacing, the pairs may be
used to interface to a Quarter VGA LCD screen using the MityDSP hardware and
software development kit LCD interface libraries and an appropriate daughterboard
interface. Off-the-shelf display solutions for QVGA interfaces are provided by Critical
Link.
