COMPONENT VIDEO PROCESSING

Component video processing supports formats including 525i,

625i, 525p, 625p, 720p, 1080i, and many other HDTV formats,

as well as automatic adjustments that include gain (contrast)

and offset (brightness), and manual adjustment controls. Other

features supported by component video processing are

•

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) enables 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 110 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 video centric back-end

IC interfacing

•

Data enable (DE) output signal supplied for direct

connection to HDMI/DVI Tx IC

•

Arbitrary pixel sampling support for nonstandard

video sources

•

RGB graphics supported on 12-bit DDR format

GENERAL FEATURES

General features of the ADV7181C include 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 are

•

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, 10 mm × 10 mm, Pb-free LQFP

•

3.3 V ADCs giving enhanced dynamic range and

performance
