ADV7611

Low Power 165 MHz HDMI Receiver

Analog Devices 

Data Sheet

FUNCTIONAL OVERVIEW

HDMI RECEIVER

The receiver supports all mandatory and many optional 3D

formats. It supports HDTV formats up to UXGA at 8 bit.

The HDMI-compatible receiver on the ADV7611 incorporates

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. It is capable of equalizing for cable lengths up to

30 meters to achieve robust receiver performance.

With the inclusion of HDCP, displays can receive encrypted

video content. The HDMI interface of the ADV7611 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.

The ADV7611 has a synchronization regeneration block used

to regenerate the DE 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 TERC4 error detection, used for detection of

corrupted HDMI packets following a cable disconnect.

The HDMI receiver 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, the audio signal can be ramped to prevent audio

clicks or pops. Audio output can be formatted to LPCM and

IEC 61937.

The HDMI receiver features include:

• 162.5 MHz (UXGA at 8 bit) maximum TMDS clock

frequency

• 3D format support defined in HDMI 1.4a specification

• Integrated equalizer for cable lengths up to 30 meters

• HDCP 1.4

• Internal HDCP keys

• PCM audio packet support

• Repeater support

• Internal EDID RAM

• Hot Plug assert output pin for an HDMI port

• CEC controller

COMPONENT PROCESSOR

The ADV7611 has an any-to-any 3 × 3 CSC matrix. The CSC

block is placed at the back of the CP section. CSC enables

YPrPb-to-RGB and RGB-to-YCrCb conversions. Many other

standards of color space can be implemented using the color

space converter.

CP features include:

• 525i, 625i, 525p, 625p, 720p, 1080i, 1080p, and other

formats

• Manual adjustments including gain (contrast) and

offset (brightness), hue, and saturation

• Free run output mode that provides stable timing when no

video input is present

• 162.5 MHz processing rate

• Contrast, brightness, hue, and saturation controls

• Standard identification enabled by STDI block

• RGB that can be color space converted to YCrCb and

decimated to a 4:2:2 format for video-centric back end IC

interfacing

• DE output signal supplied for direct connection to an

HDMI/DVI transmitter

OTHER FEATURES

The ADV7611 has HS, VS, FIELD, and DE output signals with

programmable position, polarity, and width.

The ADV7611 has programmable interrupt request output pins,

including INT1 and INT2 (INT2 is accessible only via one of

following pins: MCLK/INT2, SCLK/INT2, or HPA_A/INT2).

It also features a low power-down mode. The I2C address of

the main map is 0x98 after reset. This can be changed after reset

to 0x9A if pullup is attached to VS/FIELD/ALSB pin and I2C

command SAMPLE_ALSB is issued. Refer to the Register

Access and Serial Ports Description section in the UG-180.

The ADV7611 is provided in a 10 mm × 10 mm, RoHS-compliant

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

temperature range.
