GENERAL DESCRIPTION
The ADV7622 is a high performance, four-input, one-output,
High-Definition Multimedia Interface (HDMI) transceiver
that integrates HDMI 1.4 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 ADV7622 supports all mandatory HDMI 1.4 3D TV formats
in addition to all HDTV formats up to 1080p 36-bit Deep Color.
The ADV7622 also features an integrated HDMI 1.4 CEC
controller that supports capability, discovery, and control (CDC).
The ADV7622 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 ADV7622 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 ADV7622 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.
