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.
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
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
