Data Sheet 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.

Stresses at or above those listed under Absolute Maximum

Ratings may cause permanent damage to the product. This is a

stress rating only; functional operation of the product at these

or any other conditions above those indicated in the operational

section of this specification is not implied. Operation beyond

the maximum operating conditions for extended periods may

affect product reliability.

THERMAL RESISTANCE

To reduce power consumption when using the ADV7482, turn

off unused sections of the device.

Due to printed circuit board (PCB) metal variation, and,

therefore, variation in PCB heat conductivity, the value of θJA

may differ for various PCBs.

The most efficient measurement solution is achieved using the

package surface temperature to estimate the die temperature.

This eliminates the variance associated with the θJA value.

Do not exceed the maximum junction temperature (TJ max) of

125°C. The following equation calculates the junction

temperature (TJ) using the measured package surface

temperature and applies only when no heat sink is used on the

device under test (DUT):

TJ = TS + (ΨJT ×WTOTAL)

where:

TS is the package surface temperature (°C).

ΨJT = 0.81°C/W for the 100-ball CSP_BGA (based on 2s2p test

board defined by JEDEC standards.

WTOTAL = (PVDD × IPVDD) + (TVDD × ITVDD) − PUpStream +

(CVDD × ICVDD) + (AVDD × IAVDD) + (DVDD × IDVDD) +

(DVDDIO × IDVDDIO) + (MVDD × IMVDD)

where PUpStream is the quantity of TVDD power consumed on the

upstream HDMI transmitter. PUpStream can be estimated to be

around 110 mW for a nominal HDMI transmitter.

Data Sheet ADV7482

THOERY OF OPERATION

HDMI RECEIVER

The HDMI receiver supports video formats ranging from 480i

to 1080p, and display resolutions from VGA (640 × 480 at

60 Hz) to UXGA (1600 × 1200 at 60 Hz).

The HDMI receiver allows programmable equalization of the

HDMI data signals. This equalization compensates for the high

frequency losses inherent in HDMI and DVI cabling, especially

at longer lengths and higher frequencies. The receiver is capable

of equalizing for cable lengths up to 30 meters to achieve robust

receiver performance.

The HDMI interface of the ADV7482 allows for authentication

of a video receiver, decryption of encoded data at the receiver,

and renewability of that authentication during transmission, as

specified by the HDCP 1.4 protocol.

Dual extended display identification data (EDID) support is

provided via an on-chip 512-byte EDID RAM. The EDID RAM

must be programmed at power-up. It can be configured as two

256-byte EDIDs, or as a single 512-byte EDID.

The ADV7482 has a synchronization regeneration block used to

regenerate the data enable (DE) signal based on the measurement

of the video format being displayed and to filter the horizontal

and vertical synchronization signals to prevent glitches.

The HDMI receiver also supports TMDS error reduction

coding, 4-bit (TERC4) error detection, used for the detection of

corrupted HDMI packets.

The main HDMI receiver features include

• 162.0 MHz (UXGA at 24 BPP) maximum TMDS clock

frequency.

• Integrated fully adaptive equalizer for cable lengths up to

30 meters.

• HDCP 1.4 support.

• Internal HDCP keys.

• HDCP repeater support, up to 25 key selection vectors

(KSVs) supported.

• PCM audio packet support.

• Support for 8-channel TDM output data up to 48 kHz.

• Repeater support.

• Internal EDID RAM (512-byte for single mode, and

256-byte for dual mode operation).

• Hot Plug assert output pin (HPD).

• CEC controller.

COMPONENT PROCESSOR

The ADV7482 has one any-to-any 3 × 3 CSC matrix. The CSC

block is located in the processing path before the CP section.

CSC enables YCbCr-to-RGB and RGB-to-YCbCr conversions.

Many other standards of color space can be implemented using

the color space converter.

CP features include

• Support for all video modes supported by the HDMI

receiver. These include 525i, 625i, 525p, 625p, 1080i, 1080p,

and display resolutions from VGA (640 × 480 at 60 Hz) to

UXGA (1600 × 1200 at 60 Hz).

• Manual adjustments including gain (contrast), offset

(brightness), hue, and saturation.

• Free run output mode that provides stable timing when no

video input is present.

• Timing adjustments controls for HS/VS/DE timing.

ANALOG FRONT END

The ADV7482 AFE comprises a single high speed, 10-bit ADC

that digitizes the analog video signal before applying it to the

SDP. The AFE uses differential channels to the ADC to ensure

high performance in mixed-signal applications and to enable

differential CVBS to be connected directly to the ADV7482.

Up to eight analog inputs can be connected to the AFE. The

front end also includes an 8-channel input mux that enables

different configurations of single-ended CVBS (up to eight),

pseudo differential or fully differential CVBS (up to four), Y/C

(up to four), and YPbPr (up to two) analog inputs.

Current clamps are positioned in front of the ADC to ensure

that the video signal remains within the range of the converter.

A resistor divider network is required before each analog input

channel to ensure that the input signal is within the range of the

ADC. Figure 11 shows a typical voltage divider network for

single-ended inputs, Figure 12 shows a typical voltage divider

network for pseudo differential inputs, and Figure 13 shows a

typical voltage divider network for fully differential inputs. The

choice of the resistor divider shown in Figure 13 provides a

common-mode range of up to 4 V in fully differential CVBS

input mode. Fine clamping of the video signal is performed

downstream by digital fine clamping within the ADV7482.

ADV7482 Data Sheet

Figure 13. Typical Fully Differential Input Resistor Divider Network

The ADC features three clocking rates that allow 4×

oversampling per channel for CVBS mode, Y/C mode, and

YPbPr mode.

The fully differential AFE of the ADV7482 provides inherent

small and large signal noise rejection, improved electromagnetic

interference (EMI) protection, and the ability to absorb ground

bounce. Support is provided for both true differential and

pseudo differential signals.

The main AFE features include

• A single 172 MHz, 10-bit ADC that enables true 8-bit

video decoding.

• 8-channel analog input mux that enables multiple source

connections without the requirement of an external mux.

• A current clamp control loop that ensures that any dc

offsets are removed from the video signal entering the SDP.

• Diagnostic capability on all differential inputs.

• Support for 4 V common-mode input range.

• Support for analog input signals up to 1 V p-p.

• Support for single-ended, pseudo differential, and fully

differential inputs.

SHORT TO BATTERY DIAGNOSTICS

In differential mode, the ADV7482 is protected against STB

events by ac coupling capacitors (see Figure 12 and Figure 13).

The input network resistors are sized to reduce the current flow

during an STB event, thus preventing damage to the resistors.

Note that the input network resistors and the ac coupling

capacitors must be chosen with ratings guaranteeing they are

able to withstand the high voltage of STB events.

The four diagnostic inputs of the ADV7482 provide diagnostic

capability for all differential inputs. The ADV7482 can detect an

STB event on either the positive or the negative composite input

and trigger an interrupt. The 75 Ω (pseudo differential) or 150 Ω

(fully differential) parallel termination resistor enables one

DIAGx pin to sense an STB event on either input, because there

is a minimal voltage drop across the resistor.

Figure 14. Diagnostic Connection for Differential Inputs

Resistors R4 and R5 divide down the voltage at the input

connector to protect the DIAGx pin from an STB event. The

DIAGx pin circuitry compares this voltage to a programmable

reference voltage, known as the diagnostic slice level. When the

diagnostic slice level is exceeded, an STB event has occurred.

R4 and R5 are sized to allow the use of low cost, small footprint

resistors that are tolerant of STB events.

Use the following equation to find the STB voltage for a selected

diagnostic slice level.

EL_SLICE_LEVDIAGNOSTIC

R4R5

VRSTB_TRIGGE ×

where:

VSTB_TRIGGER is the minimum voltage required at the input

connector to trigger the STB interrupt on the ADV7482.

DIAGNOSTIC_SLICE_LEVEL is the programmable reference

voltage.

For example, with a diagnostic slice level programmed to

1.125 V, an R4 value of 9.1 kΩ, and an R5 value of 1 kΩ, the

minimum voltage required at the input connector to trigger the

STB interrupt is approximately 11.4 V.

When the DIAGx pin voltage exceeds the diagnostic slice level

voltage, a hardware interrupt is triggered and indicated by one

of the interrupt pins. A readback register specifies the input on

which the STB event occurred.

STANDARD DEFINITION PROCESSOR

The ADV7482 is capable of decoding a large selection of

baseband video signals in composite (both single-ended and

differential), S-Video, and component formats. The video

standards supported by the video processor include

• PAL B, PAL D, PAL G, PAL H, PAL I, PAL M, PAL N,

PAL Nc, and PAL 60

• NTSC J, NTSC M, and NTSC 4.43

• SECAM B, SECAM D, SECAM G, SECAM K, and SECAM L

The ADV7482 can automatically detect the video standard and

process it accordingly.

The ADV7482 has a five-line adaptive 2D comb filter that

provides superior chrominance and luminance separation when

decoding a composite video signal. This highly adaptive filter

automatically adjusts its processing mode according to the

video standard and signal quality without requiring user

intervention. Video user controls such as brightness, contrast,

saturation, and hue are also available with the ADV7482.

The ADV7482 implements the patented Adaptive Digital Line

Length Tracking (ADLLT™) algorithm to track varying video

line lengths from sources such as a VCR. ADLLT enables the

ADV7482 to track and decode poor quality video sources such

as VCRs and noisy sources from tuner outputs, VCD players,

and camcorders. The ADV7482 contains a chroma transient

improvement (CTI) processor that sharpens the edge rate of

chroma transitions, resulting in sharper vertical transitions.

The ACE of the ADV7482 offers improved visual detail using

an algorithm that automatically varies contrast levels to enhance

picture detail. ACE allows the contrast of an image to increase

depending on the content of the picture. Typically, this allows

bright areas to be made brighter and dark areas to be made

darker. However, the ADV7482 ACE feature also allows the

contrast within dark areas to increase without significantly

affecting the bright areas of the picture. This feature is

particularly useful in automotive applications, where it is

important to discern objects in shaded areas.

Down dithering converts the output of the ADV7482 from an

8-bit to a 6-bit output, enabling ease of design for standard LCD

panels.

The SDP can process a variety of VBI data services, such as

closed captioning (CCAP), wide screen signaling (WSS), and

copy generation management system (CGMS).

The ADV7482 is fully Rovi®(Macrovision®) compliant; detection

circuitry enables Type I, Type II, and Type III protection levels

to be identified and reported to the user. The decoder is also

fully robust to all Macrovision signal inputs.

8-BIT DIGITAL INPUT/OUTPUT PORT

The ADV7482 features an 8-bit digital bidirectional port. The

following formats are supported both as input and output ports:

• 8-bit interleaved 4:2:2 SDR input/output with embedded

timing codes

• 8-bit interleaved 4:2:2 DDR input/output with embedded

timing codes

The maximum input and output video resolution supported is

720p/1080i in both SDR and DDR modes.

Video received on the 8-bit digital input port can be routed to

the four-lane MIPI CSI-2 transmitter. Video sent on the 8-bit

digital output port can be routed from either the SD core or the

CP core.

AUDIO PROCESSING

The ADV7482 features an audio processor that handles the

audio extracted from the HDMI stream by the HDMI receiver.

It contains an audio mute controller that can detect a variety of

conditions that may result in audible extraneous noise in the

audio output. On detection of these conditions, a 2-channel

linear PCM audio signal can be ramped down to a mute state to

prevent audio clicks or pops.

The audio is output on a single flexible serial digital audio

output port supporting I2S-compatible, left justified, and right

justified audio output modes in master mode only. TDM is also

supported, allowing up to eight audio channels with a sample

rate up to 48 kHz to be transmitted over the single serial digital

audio interface.

MIPI CSI-2 TRANSMITTERS

The ADV7482 features two MIPI CSI-2 transmitters: a four-

lane transmitter (Transmitter A) and a single lane transmitter

(Transmitter B).

The four-lane transmitter consists of four differential data lanes

(DA0N, DA0P, DA1N, DA1P, DA2N, DA2P, DA3N and DA3P),

and a differential clock lane (CLKAN and CLKAP). It supports

four data lanes, two data lanes, and one data lane muxing

options, and can be used to transmit video received on either

the HDMI receiver (processed through the CP), the 8-bit digital

input port, or the AFE (processed through the SDP).

The main features of the four-lane MIPI transmitter

(Transmitter A) include

• Support for 8-bit and 10-bit YCbCr 4:2:2 video modes.

• Support for 24-bit RGB 4:4:4 (RGB888), 18-bit RGB 4:4:4

(RGB666), and 16-bit RGB 4:4:4 (RGB565) video modes.

• Support for video formats ranging from 480i to 1080p, and

display resolutions from VGA to UXGA (certain

restrictions apply to the muxing option, video mode, and

video format that can be selected).

• Data lanes and clock lane remapping to ease PCB layout.

The single lane transmitter consists of a single differential data

lane (DB0N and DB0P) and a differential clock lane (CLKBN

and CLKBP). It transmits video received on the AFE (processed

through the SDP).

The main features of the single lane MIPI transmitter

(Transmitter B) include

• Support for 8-bit YCbCr 4:2:2 video mode.

• Support for 480i and 576i video formats.

INTERRUPTS

The ADV7482 features two interrupt request pins. INTRQ1 and

INTRQ2 can be programmed to trigger interrupts based on

various selectable events related to the HDMI receiver (video

and audio related), the SDP, and the CP.
