ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADV473 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
T he ADV473 is capable of generating RGB video output sig-
nals, without requiring external buffering, and which are com-
patible with RS-343A and RS-170 video standards. All digital
inputs and outputs are T T L compatible.
T he part can be driven by the on-board voltage reference or an
external voltage reference.
T he part is packaged in a 68-pin Plastic Leaded Chip Carrier
(PLCC).
(Continued from page 1)
T he device consists of three, high speed, 8-bit, video D/A con-
verters (RGB), a 256
3
24 RAM which can be configured as a
look-up table or a linearization RAM, a 24-bit wide parallel
pixel input port and three 15
3
8 overlay registers. T he part is
controlled through the MPU port by the various on-board con-
trol/command registers.
T he individual red, green and blue pixel input ports allow true-
color, image rendition. T rue-color image rendition, at speeds of
up to 135 MHz, is achieved through the 24-bit pixel input port.
T he ADV473 is also capable of implementing 8-bit true color,
8-bit pseudo color and 15-bit true color.

Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. T his is a stress rating only and functional
operation of the device at these or any other conditions above those listed in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
