Host Processor Interface
The host processor basically drives the DAC; therefore, the DAC 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.
A custom cable can be made specific to the host interface platform. The EVM allows interface to the host
processor through J2 and P2 pass-through header connector for the serial control signals and the serial
data input. The output can be monitored through the J4 header connector.
A TI Interface Board is also available for a specific TI DSP Starter Kit as well as an MSP430-based
microprocessor as mentioned in
of this manual. Using the interface board foregoes the task of
building customized cables and allows easy configuration of a simple evaluation system.
This DAC EVM interfaces with any host processor capable of handling serial communication protocols or
the popular TI DSP. For more information regarding the serial interface of the particular DAC installed, see
the specific DAC data sheet, as listed in the Related Documentation from Texas Instruments section of
this user guide.
