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.
