The ADV7612 is offered in automotive, professional (no HDCP), and industrial versions. The operating temperature range is −40℃ to +85℃.
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)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. Additionally, the ADV7612 can be set to output TDM I2S, which provides four multiplexed I2S channels.
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.
