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 75 Ω load. 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. 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.
