6 Application Information
6.1 Video vs Computer Graphics Application
THS8200 is a highly integrated and flexible universal analog component video/graphics generator that can
be used in any application requiring D/A conversion of video/graphics signals.
In a typical video application (for example, DVD player, set-top box), the THS8200 receives its input from
an MPEG decoder or media processor engine and converts the signal into the analog domain, thereby
generating the correct timing/frame format for the selected format.
Its ITU-R.BT656 output port could be used to connect to an NTSC/PAL video encoder, such as the Texas
Instruments TVP6000, for regular composite/S-video output.
Note that because the DAC speed is rated up to 205 MSPS, all popular SDTV and HDTV formats,
including 1080I and 720P, are supported in both 1x and 2x interpolated modes. The 1080P is supported at
the 1x rate.
Figure 6-1. Typical Video Application
Because of its programmable Hsync/Vsync outputs, the on-chip support for RGB as well as YCbCr color
spaces and its internal color space conversion circuit, and the DAC operational speed of 205 MSPS, all
PC graphics formats are supported as well, up to UXGA at 75 Hz. Video interpolation is now bypassed so
that the full 205 MSPS can be used for the 1x pixel clock.
