C6416 DSK DAC - Use codec to convert digital input to analog output

Library

C6416 DSK Board Support in Target Support Package TC6 software

Description

Adding the C6416 DSK DAC (digital-to-analog converter) block to your Simulink model provides the means to output an analog signal to the LINE OUT connection on the C6416 DSK board. When you add the C6416 DSK DAC block, the digital signal received by the codec is converted to an analog signal. After converting the digital signal to analog form (digital-to-analog (D/A) conversion), the codec sends the signal to the output jack.

One of the configuration options in the block affects the codec. The remaining options relate to the Simulink model and the signal processor on the board. In the following table, you find each option listed with the C6416 DSK hardware affected by your selection.

Dialog Box

Word length

Sets the DAC to interpret the input data word length. Without this setting, the DAC cannot convert the digital data to analog correctly. The value defaults to 16 bits, with options of 20, 24, and 32 bits. The word length you set here should always match the ADC setting.

Sampling rate

Sets the sampling rate for the block output to the output ports on the target. Select from the list of available rates.

Scaling

Selects whether the input to the codec represents unmodified data, or data that has been normalized to the range ±1.0. Matching the setting for the C6416 DSK ADC block is usually appropriate here.

Overflow mode

Determines how the codec responds to data that is outside the range specified by the Scaling parameter. You can choose Wrap or Saturate to handle the result of an overflow in an operation. If efficient operation matters, Wrap is the more efficient mode.
