TMDXDOCK28027 Application Field and Working Principle

The TMDXDOCK28027 is an evaluation board, designed to evaluate the performance of TI’s DSP/MCU family of devices. It can be used by engineers and developers to evaluate and test the performance of the latest TI media processors, including the OMAP35x, OMAP-L138 and DaVinci DM37xx. The board consists of a motherboard, an auxiliary board and a off-board cable kit.

The main board is a high-speed, low-power device with a total of 80 I/O pins. Each of the pins is separated into 16 discrete digital I/Os in order to interface with other peripheral boards. The board has a high speed oscillator on-board for high speed signal communication, as well as analog I/O, power on and off, USB programming interface, and four user-defined push buttons on the bottom of the board. The board is powered by a 10V DC power supply.

The auxiliary board is used to interface with the MCU/DSP processor. It consists of four boards: the CPLD interface board, the Additional Peripheral Board, the Power Management board, and the Programming Board. The CPLD interface board contains a Xilinx Spartan-3 FPGA which provides an external memory interface for the MCU/DSP processor, as well as a TTL compatible UART interface for communication with peripherals. The Additional Peripheral Board adds extra features like a LCD display, an SD card slot, and an onboard RTC. The Power Management board provides power sequencing and reset generation for all the peripherals connected to the board. The Programming Board provides an easy-to-use USB interface for programming and debugging.

The off-board cables are used for interfacing with external peripherals. The board has four high-speed USB OTG ports and two SATA ports. It also has a JTAG port to connect to the debugger. The board also has an Ethernet port and an RJ45 connector for connecting to external devices.

Now let’s look at the working principle of the TMDXDOCK28027. The board works by providing power to the MCU/DSP processor, communicating with the MCU/DSP processor via the CPLD interface board, and providing external peripherals via the other auxiliary boards. The power on and programming for the board can be managed via the USB port. The board utilizes the on-board oscillator to clock the peripheral devices, and can also support external clocks using the oscillator. The board can be used to develop applications with the TI’s embedded DSP/MCU familes.

In conclusion, the TMDXDOCK28027 is a versatile evaluation board which can be used to develop applications on the TI’s DSP/MCU family of processors. It provides a range of features, including an on-board oscillator,USB ports, an Ethernet port, and JTAG debugging support. With its integrated CPLD interface, the board can be used to communication with external peripherals, while itsfour user-defined push buttons provide easier programming and debugging.
