RGB GRAPHICS PROCESSING
The ADV7604 provides automaticdetection of synchronization
source and polarity by the SSPD block, standard identification
that is enabledbytheSTDIblocks, optimumpixelsamplethrough
a 32-phase DLL, and arbitrary pixel sampling for nonstandard
video sources. A data enable (DE)outputsignal is supplied for
direct connection to the HDMI/DVItransmitter IC.
The following additional graphics functions areprovided:
Automaticor manual clamp and gain controls for
graphics modes
Contrast and brightnesscontrols
A 170 MSPS conversion ratethat supports RGB input
resolutions up to 1600 × 1200 at 60 Hz(UXGA)
Color space conversion of RGB to YCrCband decimation
to a 4:2:2 format for video-centricbackend IC interfacing
ENHANCED STANDARDDEFINITION PROCESSOR
The ESDP is designed to provide robust synchronization
separation capability for component videoinput modes that are
likely to have an unstabletime base. Theseare component signals
that have originated from CVBS signals such as noisy/weakRF
signals or VCR signalswith head switches.The ESDP is available
for SD (480i, 576i) and ED (480p, 576p) component video input
modes with embedded synchronization becausethesearemost
likely to suffer from timing impairments.
The ESDP contains circuitry for identifying characteristics of
the input signal, and these are then used within the device to
automatically configure it optimally for different inputs. It uses
digitally controlled analog clamping to maximize the range of
the video signal within the ADC. This effectively compensates
for the poor signal quality that may be present on the input.
I2C INTERFACE
The ADV7604 supports a 2-wire serial (I2C-compatible)
microprocessor busdriving multiple peripherals. The
ADV7604 is controlled by an external I2C master device,
such as a microcontroller.
OTHER FEATURES
In addition to HS, VS, and FIELD output signals with program-
mable position, polarity, andwidth, the ADV7604 provides the
following:
Programmableinterrupt request outputpins: INT1 and INT2
Low power consumption: 1.8 V digital core, 1.8 V analog
and 3.3 V digital input/output, low power power-down
mode, and green PC mode
Temperature range: 40°C to +70°C
15 mm × 15 mm, RoHS-compliant BGA package
