Using the SC70 DAC EVM With DXP
DXP is a program for controlling the digital input signals such as the clock, SYNC, and SDI. Wave tables
are built into the DSP software to allow Sine, Ramp, Triangle, and Square wave signals to be generated
by the SC70 DAC. Straight DC outputs can also be obtained.

The SC70 DAC EVM-PDK is controlled by loading a DAC EVM configuration into the MMB0. For complete
information about installing and configuring DXP, see the DXP User's Guide, available for download from
the TI Web site. This section covers the specific operation of the SC70 DAC EVM-PDK.

Hardware
The hardware consists of two main components: the first is the SC70 DAC EVM itself and the other is a
modular motherboard called the MMB0. The MMB0 board houses a TMS320VC5507 DSP which controls
the serial interface to the device loaded on the EVM board.

The hardware needs to be configured such that the SC70 DAC EVM is plugged onto the MMB0 aligning
female connectors P1, P2, and P3 (bottom side of the SC70 DAC EVM) with male connectors J4, J7, and
J5 on the MMB0.

CAUTION
Exercise caution when assembling the SC70 DAC EVM and MMB0 boards as it
is possible to misalign the connectors.

Do not connect the MMB0 to your PC before installing the DXP software as described in the DXP User’s
Guide. Installing the software ensures that the necessary drivers are properly loaded to run the hardware.
