The ADV7480WBBCZ-RL MHL 2.1 capable receiver supports a maximumpixel clock frequency of 75 MHz, allowing resolutions up to720p/1080i at 60 Hz in 24-bit mode. The ADV7480WBBCZ-RL features alink control bus (CBUS) that handles the link layer, translationlayer, CBUS electrical discovery, and display data channel(DDC) commands. The implementation of the MHL sidebandchannel (MSC) commands by the system processor can behandled either by the I2C bus, or via a dedicated serialperipheral interface (SPI) bus. A dedicated interrupt pin(INTRQ3) is available to indicate that events related to CBUShave occurred.

The ADV7480WBBCZ-RL also features an enable pin (VBUS_EN) todynamically enable or disable the output of a voltage regulator,which provides a 5 V voltage bus (VBUS) signal to the MHLsource.

The ADV7480WBBCZ-RL HDMI capable receiver supports a maximumpixel clock frequency of 162 MHz, allowing HDTV formats upto 1080p, and display resolutions up to UXGA (1600 × 1200 at60 Hz). The device integrates a consumer electronics control(CEC) controller that supports the capability discovery andcontrol (CDC) feature. The HDMI input port has dedicated 5 Vdetect and Hot Plug™ assert pins.

The HDMI/MHL receiver includes an adaptive transitionminimized differential signaling (TMDS) equalizer that ensuresrobust operation of the interface with long cables.The ADV7480WBBCZ-RL single receiver port is capable of accepting bothHDMI and MHL electrical signals. Automatic detectionbetween HDMI and MHL is achieved by using cable impedancedetection through the CD_SENSE pin.

The ADV7480WBBCZ-RL contains a component processor (CP) thatprocesses the video signals from the HDMI/MHL receiver. Itprovides features such as contrast, brightness, and saturationadjustments, as well as free run and timing adjustment controlsfor HS/VS/DE timing.

The ADV7480WBBCZ-RL features an 8-bit digital input/output port,supporting input and output video resolutions up to 720p/1080iin both the 8-bit interleaved 4:2:2 SDR and DDR modes.

To enable glueless interfacing of these video input sources to thelatest generation of infotainment system on chips (SoCs), theADV7480WBBCZ-RL features a MIPI® CSI-2 transmitter. The four-lanetransmitter provides four data lanes, two data lanes, and onedata lane muxing options, and can be used to output video fromthe HDMI receiver, the MHL receiver, and the digital inputport.

The ADV7480WBBCZ-RL offers a flexible audio output port for audio dataextracted from the MHL or HDMI streams. The HDMI/MHLreceiver has advanced audio functionality, such as a mutecontroller that prevents audible extraneous noise in the audiooutput. Additionally, the ADV7480WBBCZ-RL can be set to output timedivision multiplexing (TDM) serial audio, which allows thetransmission of eight multiplexed serial audio channels on asingle audio output interface port.

The ADV7480WBBCZ-RL is programmed via a 2-wire, serial, bidirectionalport (I2C compatible).

Fabricated in an advanced CMOS process, the ADV7480WBBCZ-RL isavailable in a 9 mm × 9 mm, RoHS-compliant, 100-ballCSP_BGA package and is specified over the −40°C to +85°Ctemperature range.

The ADV7480WBBCZ-RL is offered in automotive and industrial versions.
