GENERAL DESCRIPTION
The ADV7123 (ADV®) is a triple high speed, digital-to-analog
converter on a single monolithic chip. It consists of three
high speed, 10-bit, video D/A converters with complementary
outputs, a standard TTL input interface, and a high impedance,
analog output current source.
The ADV7123 has three separate 10-bit-wide input ports. A
single 5 V/3.3 V power supply and clock are all that are required
to make the part functional. The ADV7123 has additional video
control signals, composite SYNC and BLANK.
The ADV7123 also has a Power-Save Mode.
The ADV7123 is fabricated in a 5 V CMOS process. Its mono-
lithic CMOS construction ensures greater functionality with
lower power dissipation. The ADV7123 is available in a
48-lead LQFP package.
PRODUCT HIGHLIGHTS330 MSPS throughputGuaranteed monotonic to 10 bitsCompatible with a wide variety of high resolution color
graphics systems, including RS-343A and RS-170

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADV7123 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.

TERMINOLOGY
Blanking Level
The level separating the SYNC portion from the video portion
of the waveform. Usually referred to as the front porch or back
porch. At 0 IRE units, it is the level that will shut off the picture
tube, resulting in the blackest possible picture.
Color Video (RGB)
This usually refers to the technique of combining the three primary
colors of red, green, and blue to produce color pictures within
the usual spectrum. In RGB monitors, three DACs are required,
one for each color.
Sync Signal (SYNC)
The position of the composite video signal that synchronizes the
scanning process.
Gray Scale
The discrete levels of video signal between reference black and
reference white levels. A 10-bit DAC contains 1024 different
levels, while an 8-bit DAC contains 256.
Raster Scan
The most basic method of sweeping a CRT one line at a time to
generate and display images.
Reference Black Level
The maximum negative polarity amplitude of the video signal.
Reference White Level
The maximum positive polarity amplitude of the video signal.
Sync Level
The peak level of the SYNC signal.
Video Signal
The portion of the composite video signal that varies in gray
scale levels between reference white and reference black. Also
referred to as the picture signal, this is the portion that may be
visually observed.
