Video DAC Specifications
NOTE
For more information regarding the VideoDAC architecture, see the Display Subsystem /
Display Subsystem Functional Description / Video Encoder Functionalities / Video DAC
Stage—Architecture and Control section of AM/DM37x Technical Reference Manual
(literature number SPRUGN4).
5.1
TVOUT Buffer Mode (DAC + Buffer)
NOTE
AVDAC normal mode (DAC + Buffer), higher values of the DAC input code provided by the
Video Encoder will result in lower output voltage due to the inverting configuration of the
TVOUT Buffer. See Figure 5-4 for more details on the relation between the composite video
signal levels and the DAC code values for normal mode of operation.
In AVDAC bypass mode (DAC only), higher values of the DAC input code will result in higher
output voltage, as the TVOUT Buffer path is bypassed.
The connection for this TVOUT buffer mode (DAC + Buffer) normal mode of operation is shown in
Figure 5-1. The default mode of operation is dc coupling. For more information regarding the
recommended values of the external components, see Section 5.4, Electrical Specifications Over
Recommended Operating Conditions.
