Data Sheet

RGB GRAPHICS PROCESSING

The ADV7403 provides 140 MSPS conversion rate support of

RGB input resolutions up to 1280 × 1024 at 75 Hz (SXGA) and

110 MSPS conversion rate for the ADV7403BSTZ-110. It also

provides automatic or manual clamp and gain controls for

graphics modes.

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 arbitrary pixel sampling

support for nonstandard video sources.

Additional RGB graphics processing features of the ADV7403

include the following:

• 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.

DIGITAL VIDEO INPUT PORT

The ADV7403 supports raw 8-/10-bit CVBS data from a digital

tuner and 24-bit RGB input data from a DVI receiver chip,

output converted to YCrCb 4:2:2. It also supports 24-bit 4:4:4,

16-/20-bit 4:2:2 525i, 625i, 525p, 625p, 1080i, 720p, VGA to

SXGA at 60 Hz input data from HDMI receiver chip, output

converted to 16-bit 4:2:2 YCrCb.

GENERAL FEATURES

The ADV7403 features HS, VS, and FIELD output signals with

programmable position, polarity, and width. It also includes a

programmable interrupt request output pin (INT), signals

SDP/CP status changes, and supports two I2C host port

interfaces (control and VBI).

The ADV7403 offers low power consumption: 1.8 V digital

core, 3.3 V analog and digital input/output, low power power-

down mode, and green PC mode.

The ADV7403BSTZ-110 operates over the industrial temperature

range (−40°C to +85°C) and is available in a 100-lead, 14 mm ×

14 mm, RoHS-compliant LQFP.

It is also available in a 140 MHz speed grade (ADV7403KST-140).
