GENERAL DESCRIPTION
The ADV7604 is a high quality, single chip, multiformat video
decoder, graphics digitizer with an integrated 4:1 multiplexed
High-Definition Multimedia Interface (HDMI®) receiver.
The ADV7604 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 ADV7604 can operate in quad HDMI and
analog input mode, thus providing simultaneous HDMI and
analog video sync processing. This allows for fast switching
between HDMI and the ADCs.
The ADV7604 supports the decoding of a component RGB/
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.
Graphics digitization is also supported by the ADV7604. The
ADV7604 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 ADV7604 incorporates a quad input HDMI-compatible
receiver that supports all 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. The
HDMI receiver also includes programmable/adaptive equaliza-
tion that ensures robust operation of the interface with cable
lengths up to 30 meters. The HDMI receiver has advanced
audio functionality, such as a mute controller that prevents
audible extraneous noise in the audio output.
Fabricated in an advanced CMOS process, the ADV7604 is
provided in a space-saving, 260-ball 15 mm × 15 mm BGA
surface-mount, RoHS-compliant package and is specified
over the −40°C to +70°C temperature range.
