MityDSP Development Kit Mother Board
04-APR-2007
RS-232 Interface Description
The on-board RS-232 level driver and DB-9 connector provides standard serial interface
at data rates up to 115,200 baud. The serial interface is routed to the primary MityDSP
serial bootloading port in order to allow remote code download and FLASH upgrades on
an attached MityDSP from this connector.
USB Interface Description
The on-board USB interface leverages an asynchronous serial to USB 2.0 compliant
bridge chip that supports data rates up to 6 Mbits per second. Drivers for the USB
interface are provided with the MityDSP software development kit and are compatible
with Windows XP, 2000, and Vista. The USB serial interface is routed to the alternate
MityDSP serial bootloading port in order to allow remote code download and FLASH
upgrades on an attached MityDSP from this connector.
Ethernet Interface Description
The on-board Ethernet interface provides a network PHY capable of running at 10/100
Mbit including link auto-negotiation and includes complete MII/MDIO capability. In
industry standard RJ-45 connector is provided for external connection. Use of the
Ethernet interface requires an Ethernet media access controller implementation in the
MityDSP FPGA. The MityDSP hardware and software development kit includes a full
tested Ethernet MAC as well as an implementation of the LwIP TCP/IP stack, providing
a full Ethernet capable platform ready for integration.
The Ethernet Interface may be used to perform remote code download and FLASH
upgrades on an attached MityDSP.
ADC Description
The MDK-MB provides an on-board 8 channel 12-bit analog to digital converter to the
MityDSP TI DSP via McBSP port 1. The ADC part is the TLV2548 from Texas
Instruments / Burr Brown and is capable of sampling at rates up to 200 Ksps.
All input channels are low-pass filtered using a simple R/C network having a cut-off
frequency of TBD Hz.
Four of the eight input channels are routed (1 each) to the 4
MDK-8 daughter card slots and provide an input range of 0 to TBD volts. The remaining
four ADC input channels are brought to JTBD, an external ADC connector. Each
channel input may be configured (via jump and connector pin assignment) to provide a 0-
10V input range or a 0-2 volt input range.
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 TLV2548.
