ADV7612

GENERAL DESCRIPTION

The ADV7612 is offered in automotive, professional (no HDCP),

and industrial versions. The operating temperature range is

−40°C to +85°C.

The UG-216 contains critical information that must be used in

conjunction with the ADV7612.

The ADV7612 is a high quality Xpressview™ fast switching

HDMI®-capable receiver. It incorporates a dual input HDMI-

capable receiver that supports all mandatory 3D TV formats

defined in HDMI 1.4a specification, HDTV formats up to

1080p 36-bit Deep Color, and display resolutions up to UXGA

(1600 × 1200 at 60 Hz).

It integrates a CEC controller that supports the capability

discovery and control (CDC) feature.

The ADV7612 incorporates Xpressview fast switching on both

input HDMI ports. Using Analog Devices, Inc., hardware-based

HDCP engine that minimizes software overhead, Xpressview

technology allows fast switching between both HDMI input ports

in less than 1 second.

Each HDMI port has dedicated 5 V detect and Hot Plug™ assert

pins. The HDMI receiver also includes an integrated program-

mable equalizer that ensures robust operation of the interface

with long cables.

The ADV7612 offers a flexible audio output port for audio data

extraction from the HDMI stream. HDMI audio formats,

including SACD via DSD and HBR, are supported by ADV7612.

The HDMI receiver has advanced audio functionality, such as a

mute controller that prevents audible extraneous noise in the

audio output.

The ADV7612 contains one main component processor (CP)

that processes the video signals from the HDMI receiver. It

provides features such as contrast, brightness and saturation

adjustments, STDI detection block, free run, and synchronization

alignment controls.

Fabricated in an advanced CMOS process, the ADV7612 is

provided in a 14 mm × 14 mm, 100-lead surface-mount LQFP_EP,

RoHS-compliant package, and is specified over the −40°C to

+85°C temperature range.
