Host Processor Interface
The host processor basically drives the DAC, so the DACs proper operation depends on the successful
configuration between the host processor and the EVM board. In addition, a properly written code is also
required to operate the DAC.
configuration between the host processor and the EVM board. In addition, a properly written code is also
required to operate the DAC.
A custom cable can be made specific to any host interface platform that the EVM user chooses to use.
The EVM board allows interface to the host processor through J2 header connector for the serial control
signals and the serial data input. The output can be monitored through the J1 header connector.

To alleviate the tedious task of building customize cables, the DAC8831/32EVM is designed based on the
modular EVM form factor from Texas Instruments. This EVM form factor allows direct evaluation of the
DAC’s performance and operating characteristics in conjunction with the MMB0 Modular EVM
Motherboard and the DXP program from Texas Instruments.

This DAC EVM interfaces with any host processor capable of handling serial communication protocols or
the popular TI DSP of up to 50MHz clock speed. For more information regarding the serial interface of the
particular DAC installed, please refer to the specific DAC data sheet, as listed in
the popular TI DSP of up to 50MHz clock speed. For more information regarding the serial interface of the
particular DAC installed, please refer to the specific DAC data sheet, as listed in
of this user’s
