The ADV7480 is a combined HDMI®/MHL® receiver targeted at connectivity enabled head units requiring a wired, uncompressed digital audio/video link from smartphones and other consumer electronics devices to support streaming and integration of cloud-based multimedia content and applications into an automotive infotainment system.<br><br>The ADV7480 MHL 2.1 capable receiver supports a maximum pixel clock frequency of 75MHz, allowing resolutions up to 720p/1080i at 60Hz in 24-bit mode. The ADV7480 features a link control bus (CBUS) that handles the link layer, translation layer, CBUS electrical discovery and display data channel (DDC) commands. The implementation of the MHL sideband channel (MSC) commands by the system processor can be handled either by the I2 C bus, or via a dedicated serial peripheral interface (SPI) bus. A dedicated interrupt pin (INTRQ3) is available to indicate that events related to CBUS have occurred.<br><br>The ADV7480 also features an enable pin (VBUS_EN) to dynamically enable or disable the output of a voltage regulator, which provides a 5V voltage bus (VBUS) signal to the MHL source.<br><br>The ADV7480 HDMI capable receiver supports a maximum pixel clock frequency of 162MHz, allowing HDTV formats up to 1080p, and display resolutions up to UXGA (1600 x 1200p at 60Hz). The device integrates a consumer electronics control (CEC) controller that supports the capability discovery and control (CDC) feature. The HDMI input port has dedicated 5V detect and Hot Plug™ assert pins.
