COMPONENT VIDEO PROCESSING

Component video processing supports formats including 525i,

625i, 525p, 625p, 720p, 1080i, and many other HD formats, as

well as automatic adjustments that include gain (contrast) and

offset (brightness), and manual adjustment controls. Other

features supported by component video processing include

•

Analog component YPrPb/RGB video formats with

embedded synchronization or with separate HS, VS, or CS

•

Color space conversion matrix to support YCrCb-to-DDR

RGB and RGB-to-YCrCb conversions

•

Standard identification (STDI) to enable system level

component format detection

•

Synchronization source polarity detector (SSPD) to

determine the source and polarity of the synchronization

signals that accompany the input video

•

Certified Macrovision copy protection detection on

component formats (525i, 625i, 525p, and 625p)

•

Free-run output mode to provide stable timing when

no video input is present

•

Arbitrary pixel sampling support for nonstandard video

sources

RGB GRAPHICS PROCESSING

RGB graphics processing offers a 75 MSPS conversion rate

that supports RGB input resolutions up to 1024 × 768 at 70 Hz

(XGA), automatic or manual clamp and gain controls for

graphics modes, and contrast and brightness controls. Other

features include

•

32-phase DLL to allow optimum pixel clock sampling

•

Automatic detection of synchronization source and

polarity by SSPD block

•

Standard identification enabled by the STDI block

•

RGB that can be color space converted to YCrCb and

decimated to a 4:2:2 format for videocentric back-end

IC interfacing

•

Data enable (DE) output signal supplied for direct

connection to HDMI®/DVI transmitter IC

•

Arbitrary pixel sampling support for nonstandard video

sources

•

RGB graphics supported on 12-bit DDR format

GENERAL FEATURES

The ADV7181D features HS/CS, VS, and FIELD/DE output

signals with programmable position, polarity, and width, as well

as a programmable interrupt request output pin, INT, that signals

SDP/CP status changes. Other features include

•

Low power consumption: 1.8 V digital core, 3.3 V analog

and digital I/O, low power, power-down mode, and green

PC mode

•

Industrial temperature range of −40°C to +85°C

•

64-lead, 9 mm × 9 mm, Pb-free LFCSP

•

3.3 V ADCs giving enhanced dynamic range and

performance
