The ADV7680 is a high quality, single input HDMI® and single input ITU-R BT.656 receiver with an APIX®2 transmitter, compati-ble with APIX2 receiver technology from Inova Semiconductors. It incorporates a single port HDMI receiver that supports all mandatory and many optional 3D TV formats defined in the HDMI standard. The ITU-R BT.656 8-bit receiver supports resolutions up to 720p when using a 148.5 MHz input clock. A standard ITU-R BT.656 input clock of 27 MHz 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 On the HDMI input, the ADV7680 supports DVI or HDMI resolutions up to a 107 MHz pixel clock at 24 BPP or a 140 MHz pixel clock at 18 BPP. However, the input format configuration for both video interfaces must be managed to ensure that the maximum total video payload for the APIX2 interface is not exceeded.
The ADV7680 integrates a consumer electronics control (CEC) controller that supports the capability discovery and control (CDC) feature.
The ADV7680 has an audio output port for the audio data extracted from the HDMI input stream. The HDMI receiver also has an advanced mute controller that prevents audible extraneous noise (pops and clicks) in the audio output. Additionally, the ADV7680 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.
The following HDMI source audio formats are accessible as outputs from the ADV7680:
The following audio formats are supported as inputs to the ADV7680 for transmission over the APIX2 interface:
The HDMI input port has 5 V detect and Hot Plug™ assert pins. The HDMI receiver also includes an integrated equalizer that ensures the robust operation of the interface with long cables, including support for Type E automotive cable assemblies and connectors.
The ADV7680 contains a main component processor (CP) that processes the video signals from the HDMI receiver port. The ADV7680 provides features such as contrast, brightness, and saturation adjustments; a standard identification (STDI) detec-tion block; and free run and synchronization alignment controls.
Fabricated in an advanced CMOS process, the ADV7680 is provided in a 9 mm × 9 mm, 64-lead surface-mount LFCSP RoHS-compliant package and is specified over the −40°C to +85°C temperature range.
The ADV7680 is offered in automotive, industrial version.
