AD9388A
FUNCTIONAL OVERVIEW
The following overview provides a brief description of the
functionality of the AD9388A. More details are available in the
Theory of Operation section.
ANALOG FRONT END
The analog front end of the AD9388A provides three high quality
10-bit ADCs to enable true 10-bit video decoding, a multiplexer
with 12 analog input channels to enable a multisource connection
without the requirement of an external multiplexer, and three
current and voltage clamp control loops to ensure that dc offsets
are removed from the video signal.
HDMI RECEIVER
The AD9388A is compatible with the HDMI 1.3 specification.
The AD9388A supports all HDTV formats up to 1080p in
nondeep color mode and 1080p in 36-bit deep color mode.
Furthermore, it supports all display resolutions up to UXGA
(1600 × 1200 at 60 Hz).
This device includes the following features:
•

•
COMPONENT PROCESSOR PIXEL DATA
OUTPUT MODES
The AD9388A features single data rate outputs as follows:
•
•
•
COMPONENT VIDEO PROCESSING
The AD9388A supports 525i, 625i, 525p, 625p, 720p, 1080i,
1080p, and many other HDTV formats; automatic adjustment
of gain (contrast) and offset (brightness); manual adjustment
controls; analog component YPrPb/RGB video formats with
embedded synchronization or with separate HS, VS, or CS;
YCrCb-to-RGB and RGB-to-YCrCb conversions by any-to-any,
3 × 3, color-space conversion matrices; and user-defined pixel
sampling for nonstandard video sources.
Adaptive front-end equalization for HDMI operation over
cable lengths of up to 30 meters.
Synchronization conditioning for higher performance in
strenuous conditions.
Audio mute for removing extraneous noises.
Programmable data island packet interrupt generator.
8-/10-bit 4:2:2 YCrCb for 525i, 625i.
16-/20-bit 4:2:2 YCrCb for all standards.
24-/30-bit 4:4:4 YCrCb/RGB for all standards.

In addition, the AD9388A features brightness, saturation, and
hue controls. System level component format detection is
enabled by standard identification (STDI), and a synchroniza-
tion source polarity detector (SSPD) determines the source and
polarity of the synchronization signals that accompany the
input video.
Certified Macrovision® copy-protection detection is available on
component formats (525i, 625i, 525p, and 625p).
When no video input is present, stable timing is provided by the
free run output mode.
RGB GRAPHICS PROCESSING
The AD9388A provides 170 MSPS conversion rate support of
RGB input resolutions up to 1600 × 1200 at 60 Hz (UXGA).
The AD9388A offers automatic or manual clamp and gain controls
for graphics modes.
Similar to the component video processing features, the RBG
graphics processing for the AD9388A features contrast and
brightness controls, automatic detection of synchronization
source and polarity by the SSPD block, standard identification
enabled by the STDI block, and user-defined pixel sampling
support for nonstandard video sources.
Additional RGB graphics processing features of the AD9388A
include the following:

GENERAL FEATURES
The AD9388A offers a high quality multiformat video decoder
and digitizer that features HS, VS, and FIELD output signals
with programmable position, polarity, and width; program-
mable interrupt request output pins (INT1 and INT2); low
power consumption: 1.8 V digital core and analog input, 3.3 V
digital input/output, low power power-down mode; and a
temperature range of −40°C to +85°C in a 144-lead, 20 mm ×
20 mm, RoHS-compliant LQFP.
Sampling PLL clock with 500 ps p-p jitter at 150 MSPS.
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 HDMI/DVI transmitter IC.
