ADV7482

GENERAL DESCRIPTION

The ADV7482 is an integrated video decoder and HDMI®

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.

The ADV7482 HDMI capable receiver supports a maximum

pixel clock frequency of 162 MHz, allowing HDTV formats up

to 1080p, and display resolutions up to UXGA (1600 × 1200 at

60 Hz). The device integrates a consumer electronics control

(CEC) controller that supports the capability discovery and

control (CDC) feature. The HDMI input port has dedicated 5 V

detect and Hot Plug™ assert pins.

The HDMI receiver includes an adaptive transition minimized

differential signaling (TMDS) equalizer that ensures robust

operation of the interface with long cables.

The ADV7482 contains a component processor (CP) that

processes the video signals from the HDMI receiver. It provides

features such as contrast, brightness, and saturation

adjustments, as well as free run and timing adjustment controls

for HS/VS/DE timing.

The ADV7482 analog front end (AFE) comprises a single high

speed, 10-bit analog-to-digital converter (ADC) that digitizes

the analog video signal before applying it to the SDP.

The eight analog video inputs can accept single-ended, pseudo

differential, and fully differential composite video signals, as

well as S-Video and YPbPr video signals, supporting a wide

range of consumer and automotive video sources.

Short to battery (STB) events can be detected on differential

input video signals. STB protection is provided by ac coupling

the input video signals. The ADV7482, in combination with an

external resistor divider, provides a common-mode input range

of 4 V, enabling the removal of large signal common-mode

transients present on the video lines.

The automatic gain control (AGC) and clamp restore circuitry

allow an input video signal up to 1.0 V p-p at the analog video

input pins of the ADV7482. Alternatively, the AGC and clamp

restore circuitry can be bypassed for manual settings.

The SDP of the ADV7482 is capable of decoding a large

selection of analog baseband video signals in composite, S-Video,

and component formats. The SDP supports worldwide NTSC,

PAL, and SECAM standards.

The ADV7482 features an 8-bit digital input/output port,

supporting input and output video resolutions up to 720p/1080i

in both the 8-bit interleaved 4:2:2 SDR and DDR modes.

To enable glueless interfacing of these video input sources to the

latest generation of infotainment system on chips (SoCs), the

ADV7482 features two MIPI® CSI-2 transmitters. The four-lane

transmitter provides four data lanes, two data lanes, and one

data lane muxing options, and can be used to output video from

the HDMI receiver, the SDP, and the digital input port. The

single-lane transmitter can be used to output video from the

SDP only.

The ADV7482 offers a flexible audio output port for audio data

extracted from HDMI streams. The HDMI receiver has

advanced audio functionality, such as a mute controller that

prevents audible extraneous noise in the audio output.

Additionally, the ADV7482 can be set to output time division

multiplexing (TDM) serial audio, which allows the transmission

of eight multiplexed serial audio channels on a single audio

output interface port.

The ADV7482 is programmed via a 2-wire, serial, bidirectional

port (I2C compatible).

Fabricated in an advanced CMOS process, the ADV7482 is

available in a 9 mm × 9 mm, RoHS-compliant, 100-ball

CSP_BGA package and is specified over the −40°C to +85°C

temperature range.

The ADV7482 is offered in automotive and industrial versions.
