Figure 3. MMB0 Initial Setup

Step 3. Plug the ADS7953EVM into the MMB0. The female portion of P1, P2 and P3 on the EVM align

with male connectors J7, J4 and J5 respective on the MMB0.

CAUTION Do not misalign the pins when plugging the ADS7953EVM into the MMB0. Check the pin

alignment of P1, P2, and P3 carefully before applying power to the PDK.

Step 4. Verify the jumpers on the ADS7953EVM are as shown in Figure 2 (note that these settings are the

factory-configured settings for the EVM).

About the MMB0

The MMB0 is a Modular EVM System motherboard. It is designed around the TMS320VC5507, a DSP

with an onboard USB interface from Texas Instruments. The MMB0 also has 16MB of SDRAM installed.

The MMB0 is not intended to be used as a DSP development board, and it is not available separately. TI

cannot offer support for the MMB0 except as part of an EVM-PDK kit. For schematics or other information

about the MMB0, contact Texas Instruments.

Connecting the Power Supply

The ADS7953EVM-PDK can be operated with a unipolar +5V supply or a combination of +5V and +3.3V

supplies.

When the MMB0 DSP is powered properly, LED D2 glows green. The green light indicates that the 3.3V

supply for the MMB0 is operating properly. (It does not indicate that the EVM power supplies are

operating properly.)
