4 / 12 page ADV473 –4– REV. A RECOMMENDED OPERATING CONDITIONS Parameter Symbol Min Typ Max Units Power Supply VAA 4.75 5.00 5.25 Volts Ambient Operating Temperature TA 0 +70 °C Output Load RL 37.5 Ω Reference Voltage VREF 1.14 1.235 1.26 Volts CAUTION 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. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. The 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 TTL compatible. The part can be driven by the on-board voltage reference or an external voltage reference. The part is packaged in a 68-pin Plastic Leaded Chip Carrier (PLCC). (Continued from page 1) The device consists of three, high speed, 8-bit, video D/A con- verters (RGB), a 256 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 8 overlay registers. The part is controlled through the MPU port by the various on-board con- trol/command registers. The individual red, green and blue pixel input ports allow true- color, image rendition. True-color image rendition, at speeds of up to 135 MHz, is achieved through the 24-bit pixel input port. The ADV473 is also capable of implementing 8-bit true color, 8-bit pseudo color and 15-bit true color.

This 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. 2Analog output short circuit to any power supply or common can be of an indefinite duration.
