 | ADV101: CMOS 80 MHz, Triple 8-Bit Video DAC The ADV101 is a digital-to-analog video converter on a single monolithic chip. The part is specifically designed for high resolution color graphics and video systems. It consists of three, high speed, 8-bit, video D/A converters (RGB); a standard TTL input interface and high impedance, analog output, current sources. The ADV101 has three separate, 8-bit, pixel input ports, one each for red, green and blue video data. Additional video input controls on the part include sync, blank and reference white. A single +5 V supply, an external 1.23 V reference and pixel clock input are all that are required to make the part operational. The ADV101 is capable of generating RGB video output signals, which are compatible with RS-343A and RS-170 video standards, without requiring external buffering. |

VP101: 30/50MHz 8-BIT CMOS VIDEO DAC
The VP101 is a CMOS 8-bit video DAC designed for
use in high performance, high resolution colour graphics
applications.
The device uses video control inputs (BLANK, SYNC
and REF WHITE) to provide the VP101 with the video
pedestal levels required to generate RS-343A compatible
video signals into a doubly-terminated 75
W load, or alternatively to produce RS-170 video signals across a singly-terminated 75 W load. Data and control inputs are fully pipelined to maintain synchronisation between the DAC outputs. The full scale output current is defined by a 1.2V reference and a single resistor. |
