ADV7441ABSTZ-110 AD [Analog Devices], ADV7441ABSTZ-110 Datasheet - Page 15

• Manufacturer Part Number: ADV7441ABSTZ-110
• Description: 10-Bit Integrated, Multiformat SDTV/HDTV Video Decoder, RGB Graphics Digitizer, and 2:1 Multiplexed HDMI/DVI Interface
• Manufacturer: AD [Analog Devices]

COMPONENT VIDEO PROCESSING
The ADV7441A supports 525i, 625i, 525p, 625p, 720p, 1080i,
1080p, and many other HDTV formats; automatic adjustments
for gain (contrast) and offset (brightness); manual adjustment
controls; analog component YPrPb/RGB video formats with
embedded synchronization or with separate HS, VS, and CS;
and YCrCb-to-RGB and RGB-to-YCrCb conversions by any-to-
any, 3 × 3, color-space conversion matrices.
In addition, the ADV7441A features brightness, saturation, and
hue controls. Standard identification (STDI) enables detection
of the component format at the system level, and a synchroniza-
tion source polarity detector (SSPD) determines the source and
polarity of the synchronization signals that accompany the
input video.
Certified Macrovision copy protection detection is available on
component formats (525i, 625i, 525p, and 625p).
When no video input is present, free-run output mode provides
stable timing.
The ADV7441A supports user-defined pixel sampling for
nonstandard video sources and arbitrary pixel sampling
for nonstandard video sources.

RGB GRAPHICS PROCESSING
The ADV7441A provides 170 MSPS conversion rate support of
RGB input resolutions up to 1600 × 1200 @ 60 Hz (UXGA) and
automatic or manual clamp and gain controls for graphics models.
The RGB graphics processing functionality features contrast
and brightness controls, automatic detection of synchronization
source and polarity by the SSPD block, standard identification
enabled by the STDI block, and user-defined pixel sampling
support for nonstandard video sources.
Additional RGB graphics processing features of the ADV7441A
include the following:

GENERAL FEATURES
The ADV7441A features HS, VS, and FIELD output signals with
programmable position, polarity, and width; and programmable
interrupt request output pins, INT1 and INT2.
The part also offers low power consumption: 1.8 V digital core,
1.8 V analog, and 3.3 V digital input/output and low power power-
down mode.
The ADV7441A operates over a temperature range of −40°C
to +85°C and is available in a 144-lead, 20 mm × 20 mm, RoHS-
compliant LQFP.
Sampling PLL clock with 500 ps p-p jitter at 170 MSPS.
32-phase DLL support of optimum pixel clock sampling.
Color-space conversion of RGB to YCrCb and decimation
to a 4:2:2 format for videocentric back-end IC interfacing.
Data enable (DE) output signal supplied for direct
connection to the HDMI/DVI transmitter IC.
