GENERAL DESCRIPTIONThe ADV7121/ADV7122 (ADV®) is a video speed, digital-to-
analog converter on a single monolithic chip. The part is specifi-
cally designed for high resolution color graphics and video
systems including high definition television (HDTV). 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.
The 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. The ADV7122
has additional video control signals, composite SYNC and BLANK.
The ADV7121/ADV7122 is capable of generating RGB video
output signals which are compatible with RS-343A, RS-170 and
most proposed production system HDTV video standards, in-
cluding SMPTE 240M.
The ADV7121/ADV7122 is fabricated in a +5 V CMOS pro-
cess. Its monolithic CMOS construction ensures greater func-
tionality with low power dissipation. The ADV7121 is packaged
in a 0.6", 40-pin plastic DIP package. The ADV7122 is pack-
aged in a 44-pin plastic leaded (J-lead) chip carrier, PLCC,
and 48-lead thin quad flatpack (TQFP).
PRODUCT HIGHLIGHTS1. 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.
ADV7121–SPECIFICATIONSNOTESTemperature range (TMIN to TMAX): 0°C to +70°C.Sample tested at +25°C to ensure compliance.TTL input values are 0 to 3 volts, with input rise/fall times ≤ 3 ns, measured between the 10% and 90% points. Timing reference points at 50% for inputs and
outputs. See timing notes in Figure 1.This includes effects due to clock and data feedthrough as well as RGB analog crosstalk.
