GENERAL DESCRIPTION
The AD9388A is a high quality, single-chip graphics digitizer
with an integrated 2:1 multiplexed HDMI™ receiver.
The AD9388A contains one main component processor (CP)
that processes YPrPb and RGB component formats, including
RGB graphics. The CP also processes the video signals from the
HDMI receiver. The AD9388A can keep the HDCP link between
an HDMI source and the selected HDMI port active in analog
mode operation. This allows for fast switching between the
analog and HDMI modes.
The AD9388A supports the decoding of a component RGB or
YPrPb video signal into a digital YCrCb or RGB pixel output
stream. The support for component video includes 525i, 625i,
525p, 625p, 720p, 1080i, 1080p, and 1250i standards, as well as
many other HD and SMPTE standards.
Graphic digitization is also supported by the AD9388A. The
AD9388A is capable of digitizing RGB graphics signals from
VGA to UXGA rates and converting them into a digital RGB
or YCrCb pixel output stream.
The AD9388A incorporates a dual input, HDMI 1.3-compatible
receiver that supports HDTV formats up to 1080p and display
resolutions up to UXGA (1600 × 1200 at 60 Hz). The reception
of encrypted video is possible with the inclusion of HDCP. In
addition, the inclusion of adaptive equalization ensures robust
operation of the interface with cable lengths up to 30 meters. The
HDMI receiver has an advanced audio functionality, such as a
mute controller that prevents audible extraneous noise in the
audio output.
Derivative parts of the AD9388A are available; AD9388ABSTZ-
A5 is composed of one analog and one digital input. To facili-
tate professional applications, where HDCP processing and
decryption are not required, the AD9388ABSTZ-5P derivative
is available. This allows users who are not HDCP adopters to
purchase the AD9388A. See the Ordering Guide for details on
these derivative parts.
Fabricated in an advanced CMOS process, the AD9388A is
available in a space saving, 144-lead, surface-mount, RoHS-
compliant, plastic LQFP and is specified over the −40°C to
+85°C temperature range.
