GENERAL DESCRIPTION
The ADV7623 is a high performance, four-input, one-output,
High-Definition Multimedia Interface (HDMI®) transceiver
that integrates HDMI receiver and transmitter functions with
digital audio I/Os onto one chip. It supports all HDCP repeater
functions through fully tested Analog Devices, Inc., repeater
software libraries and drivers.
The ADV7623 incorporates Xpressview™ fast switching on all
input HDMI ports. Using an Analog Devices hardware-based
HDCP engine that minimizes software overhead, Xpressview
technology allows fast switching between any HDMI input
ports in less than 1 second.
The ADV7623 supports all mandatory HDMI 3D TV formats in
addition to all HDTV formats up to 1080p 36-bit Deep Color. The
ADV7623 also features an integrated HDMI CEC controller that
supports capability, discovery, and control (CDC).
The ADV7623 has an integrated on-screen display (OSD) feature
that allows generation and control of high quality character- and
icon-based system status and control displays. Customers interested
in using OSD are provided with Analog Devices OSD SDK.
The ADV7623 offers a dedicated flexible audio output port and
a dedicated audio input port to allow for easy extraction and
insertion of audio data into and out of the HDMI stream. HDMI
audio formats, including SACD via DSD and compressed high
bit rate audio via HBR, are supported. The ADV7623 also features
an audio return channel (ARC) receiver. ARC simplifies cabling
by combining upstream audio capability in a conventional
HDMI cable.
Fabricated in an advanced CMOS process, the ADV7623 is
provided in a 144-lead, 20 mm × 20 mm, Pb-free LQFP and is
specified over the 0°C to 70°C temperature range.
