THS8200/10 is a complete video ‘backend’ D/A solution for DVD players, personal video recorders and settop
boxes, or any system requiring the conversion of digital component video signals into the analog domain.
THS8200/10 can accept a variety of digital input formats, in both 4:4:4 and 4:2:2 formats, over a 3x10bit, 2x10bit
or 1x10 bit interface. The device synchronizes to incoming video data through either dedicated Hsync/Vsync
inputs or through extraction of the sync information from embedded sync (SAV/EAV) codes inside the video
stream. Alternatively, when configured for generating PC graphics output, THS8200/10 also provides a ‘master
timing’ mode in which it will request video data from an external (memory) source.
THS8200/10 contains a display timing generator that is completely programmable for all standard and non-
standard video formats up to the maximum supported pixelclock of 205MSPS. Therefore the device supports all
component video and PC graphics (VESA) formats. A fully-programmable 3x3 matrixing operation is included for
color space conversion. All video formats, up to the HDTV 1080I and 720P formats, can also be internally 2x
oversampled. Oversampling relaxes the need for sharp external analog reconstruction filters behind the DAC
and improves the video frequency characteristic.
The output compliance range can be set via external adjustment resistors and there is a choice of two settings,
in order to accommodate without hardware changes e.g. both component video/PC graphics (700mV) and
composite video (1.3V) outputs. An internal programmable clip/shift/multiply-function on the video data
guarantees standards-compliant video output ranges for either full 10bit or reduced ITU-R.BT601 style video
input. In order to avoid non-linearities after scaling of the video range, the DACs are internally of 11-bit
resolution. Furthermore, a bi- or tri-level sync with programmable amplitude (in order to support both 700/300mV
and 714/286mV video/sync ratios) can be inserted on either only the green/luma channel or on all three output
channels. This sync insertion is generated from additional current sources in the DACs such that the full DAC
resolution remains available for the video range. This preserves 100% of the DAC’s 11-bit dynamic range for
video data.
THS8200/10 optionally supports the pass-through of ancillary data embedded in the input video stream or can
insert ancillary data into the 525P analog component output acc. to the CGMS data specification. In addition to
all THS8200 functions, THS8210 includes the optional embedding of the Macrovision
TM 525P copy protection
system into the analog output.
