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 proposed 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 28lead small outline IC (SOIC). PRODUCT HIGHLIGHTS 1. Fast vide...
