Application information
Video vs computer graphics application
THS8200/10 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 (e.g. DVD
player, settop-box), THS8200/10 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 since the DAC speed is rated up to 205MSPS, all popular SDTV and HDTV formats, including 1080I and
720P, are supported in both 1x and 2x interpolated modes. 1080P is supported at 1x rate.
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’s operational speed of 205MSPS, all
PC graphics formats are supported as well,
up to UXGA@75Hz. Video interpolation is
now bypassed so that the full 205MSPS
can be used for the 1x pixelclock.
