APPLICATION INFORMATION
CONFIGURING THS8134 FOR GENERATING SMPTE COMPLIANT SIGNALS
Table 6 lists the standards that relate to the definition of analog interfaces for component video signals.

TITLE
SCOPE
SMPTE 253M
3-channel RGB Analog Video Interface
Component analog video for studio applications using 525 lines, 59.94
fields, 2:1 interlace and 4:3 or 16:9 aspect ratio.
SMPTE 274M
1920x1080 Scanning and Analog and Parallel
Digital Interfaces for Multiple-Picture Rates
Definition of image format of 1920x1080 pixels inside a total raster of 1125
lines, with an aspect ratio of 16:9. Interlaced format used for 1080I display
definition of the ATSC HDTV standard.
SMPTE 296M
1280x720 Scanning, Analog and Digital
Representation and Analog Interface
Definition of image format of 1280x720 pixels inside a total raster of 750
lines, with an aspect ratio of 16:9. Progressive format used for 720P
display definition of the ATSC HDTV standard.
THS8134 can be used to generate output signals compliant to each of these standards. The configuration for
each is detailed below. In each of the cases the current output of each DAC can be converted into
standard-compliant voltage levels by connecting a double terminated 75
load, as shown in the top part of
Figure 11.

SMPTE 253M
This standard defines a component analog video interface using GBR color signals carried on parallel channels
for the interconnection of television equipment. The scanning structure is typically 525 lines, 59.94 fields, 2:1
interlace and 4:3 or 16:9 aspect ratio. The analog signals of this standard are suitable for the generation of, or
they can be generated from, digital video signals compliant to SMPTE 125M and SMPTE 267M by A/D or D/A
conversion respectively. Furthermore SMPTE 253M signals can be the input to NTSC composite encoders
compliant with SMPTE 170M. Table 7 lists the scope of the standards mentioned.
