Box 9106, Norwood, MA 02062-9106, U.S.A. Tel: 617/329-4700 Fax: 617/326-8703 FUNCTIONAL BLOCK DIAGRAM I OUT CLOCK ADV7128 D0 D9 10 FS ADJUST 10 V AA REFERENCE AMPLIFIER COMP DAC DATA REGISTER GND V REF PRODUCT HIGHLIGHTS 1. Fast video refresh rate, 80 MHz. 2. Guaranteed monotonic to 10 bits. Ten bits of resolution al- lows for implementation of linearization functions such as gamma correction and contrast enhancement. 3. Compatible with a wide variety of high resolution color graphics systems including RS-343A/RS-170 and the pro- posed SMPTE 240M standard for HDTV. 4. Combined with a numerically controlled oscillator (AD9955), it forms a complete frequency synthesizer (DDS). 5. Using the parts reduced power output DAC modes, it is ideal for power and cost sensitive communications type applications. GENERAL DESCRIPTION The ADV7128 (ADV®) is a video speed, digital-to-analog con- verter on a single monolithic chip. It consists of a high speed, 10-bit, video D/A converters; a standard TTL input interface; and a high impedance, analog output, current source. The ADV7128 has a 10-bit pixel input port. A single +5 V power supply, an external 1.23 V reference and pixel clock input are and all that are required to make the part operational. The ADV7128 is capable of generating video output signals which are compatible with RS-343A, RS-170 and most pro- posed production system HDTV video standards, including SMPTE 240M. The ADV7128 is fabricated in a +5 V CMOS process. Its monolithic CMOS construction ensures greater functionality with low power dissipation. The ADV7128 is available in a 28- lead small outline IC (SOIC). ADV is a registered trademark of Analog Devices, Inc.
