GENERAL D ESCRIP TIO N

T he ADV7121/ADV7122 (ADV^®) is a video speed, digital-to-

analog converter on a single monolithic chip. T he part is specifi-

cally designed for high resolution color graphics and video

systems including high definition television (HDT V). It is also

ideal for any application requiring a low cost, high speed DAC

function especially in communications. It consists of three, high

speed, 10-bit, video D/A converters (RGB), a standard TTL input

interface and high impedance, analog output, current sources.

T he ADV7121/ADV7122 has three separate, 10-bit, pixel input

ports, one each for red, green and blue video data. A single +5 V

power supply, an external 1.23 V reference and pixel clock input is

all that is required to make the part operational. T he ADV7122

has additional video control signals, composite SYNC and BLANK.

T he ADV7121/ADV7122 is capable of generating RGB video

output signals which are compatible with RS-343A, RS-170 and

most proposed production system HDT V video standards, in-

cluding SMPT E 240M.

aged in a 44-pin plastic leaded (J-lead) chip carrier, PLCC,

and 48-lead thin quad flatpack (T QFP).

T he ADV7121/ADV7122 is fabricated in a +5 V CMOS pro-

cess. Its monolithic CMOS construction ensures greater func-

tionality with low power dissipation. T he ADV7121 is packaged

in a 0.6", 40-pin plastic DIP package. T he ADV7122 is pack-
