THS8200 Datasheet, PDF (9/97 Pages) Texas Instruments – ALL FORMAT OVERSAMPLED COMPONENT VIDEO/PC GRAPHICS D/A SYSTEM WITH THREE 11-BIT DACS,CGMS DATA INSERTION

• Programmable digital fine-gain controller on each analog output channel, for accurate channel matching
and programmable white-balance control
• Built-in 4:2:2 to 4:4:4 video interpolation filter
• Built-in 2× oversampling SDTV/HDTV interpolation filter for improved video frequency characteristic
• Fully programmable digital color space conversion circuit
• Fully programmable display timing generator to supply all SDTV and HDTV composite sync timing formats,
progressive and interlaced
• Fully programmable Hsync/Vsync outputs
• Vertical blanking interval (VBI) override or data pass-thru for VBI data transparency
• Programmable CGMS data generation and insertion
Output
• Digital
– ITU-R BT.656 digital video output port
• Analog
– Analog component output from software-switchable 700 mV/1.3 V compliant output DACs at 37.5 Ω
load
– Programmable video/sync ratio (7:3 or 10:4)
– Programmable video pedestal
General
• Built-in video color bar test pattern generator
• Fast mode I²C control interface
• Configurable master or slave timing mode
– Configuration modes allow the device to act as a master timing source for requesting data from, e.g., the
video frame buffer. Alternatively, the device can slave to an external timing master. (Master mode only
available for PC graphics output modes).
