The ADV7682 is a high quality dual input HDMI® and single input ITU-R BT.656 receiver with an APIX®2 transmitter, compatible with APIX® and APIX2 receiver technology from Inova Semiconductors. It incorporates dual port HDMI receivers that support all mandatory 3D TV formats defined in HDMI. The ITU-R BT.656 8-bit receiver supports resolutions up to 720p when using a 148.5MHz input clock. A standard ITU-R BT.656 input clock of 27MHz is also supported. When using the ITU-R BT.656 interface, only embedded timing is supported. There is no provision for using separate horizontal sync (Hsync) or vertical sync (Vsync) inputs. The ADV7682 also supports DVI or HDMI resolutions up to a 107MHz pixel clock at 24 BPP or a 140MHz pixel clock at 18 BPP. However, the input format configuration across both video ports must be managed to ensure that the maximum total video payload for the APIX2 interface is not exceeded.

ADV7682 integrates a CEC controller that supports the capability discovery and control (CDC) feature.

The ADV7682 has an audio output port for the audio data extracted from any one of the HDMI input streams. The HDMI receiver also has an advanced mute controller that prevents audible extraneous noise (pops and clicks) in the audio output. Additionally, the ADV7682 can be set to output TDM serial audio, which allows transmission of four multiplexed stereo serial audio channels on a single audio output interface port.
