Description  
The TMC22x91 digital video encoders convert digital com-  
puter image or graphics data (in RGB, YCBCR, or color  
indexed format) or a CCIR-601 signal into a standard analog  
baseband television (NTSC or PAL) signal with a modulated  
color subcarrier.  
• 8-bit mask register  
• 8-bit composite digital video input  
• Hardware and 24-bit data keying  
• Synchronizes with TMC22071 Genlocking Video  
Digitizer  
• 8:8:8 video reconstruction  
• SMPTE 170M NTSC or CCIR Report 624 PAL  
compatible  
• Supports PAL-M and NTSC without pedestal  
• Simultaneous S-VIDEO (Y/C) NTSC/PAL output  
• 10-bit D/A conversion (three channels)  
Both composite (single lead) and S-VIDEO (separate  
chroma and luma) formats are active simultaneously at the  
three analog output pins, each of which generates a standard  
video-level signal into doubly-terminated 75load.  
The TMC22x91 accepts digitized video from the companion  
TMC22071 Genlocking Video Digitizer. Soft switching  
between video sources is done under either hardware or  
programmable data control.  
The TMC22191 offers 4-layer keying capability, bypassable  
CLUT, and 30 Overlay colors.  
Logic Symbol  
The TMC22x91 is fabricated in a submicron CMOS process  
and packaged in an 84 Lead Plastic Leadless Chip Carrier, or  
in a 100 Lead Metric Quad Flat Pack. Performance is guar-  
anteed from 0°C to 70°C.
