Data Sheet
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

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

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
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
