FUNCTIONAL OVERVIEW

HDMI RECEIVER

The HDMI receiver supports all mandatory and many optional

3D video formats defined in the HDMI 1.4a specification, HDTV

formats up to 2160p, and all display resolutions up to 4k × 2k

(3840 × 2160 at 30 Hz).

With the inclusion of HDCP, displays can now receive encrypted

video content. The HDMI interface of the ADV7619 allows for

authentication of a video receiver, decryption of encoded data at

the receiver, and renewability of that authentication during trans-

mission, as specified by the HDCP 1.4 specification.

The HDMI-compatible receiver on the ADV7619 allows active

equalization of the HDMI data signals. This equalization compen-

sates for the high frequency losses inherent in HDMI and DVI

cabling, especially at longer cable lengths and higher frequencies.

The HDMI-compatible receiver is capable of equalizing for cable

lengths up to 30 meters to achieve robust receiver performance.

The ADV7619 also supports TERC4 error detection, which is

used for detection of corrupted HDMI packets following a cable

disconnect.

The HDMI receiver offers advanced audio functionality. The

receiver contains an audio mute controller that can detect a variety

of conditions that may result in audible extraneous noise in the

audio output. Upon detection of these conditions, the audio signal

can be ramped down or muted to prevent audio clicks or pops.

The HDMI receiver supports the reception of all types of audio

data described in the HDMI specifications, including

•

LPCM (uncompressed audio)

•

IEC 61937 (compressed audio)

•

DSD audio (1-bit audio)

•

HBR audio (high bit rate compressed audio)

Xpressview fast switching can be implemented with full HDCP

authentication available on the background port. Synchroniza-

tion measurement and status information are available for all

HDMI inputs. HDMI receiver features include

Hot Plug assert output pin for each HDMI port

•

CEC controller

COMPONENT PROCESSOR (CP)

The ADV7619 has two any-to-any, 3 × 3 color space conversion

(CSC) matrices. The first CSC block is placed in front of the CP

section. The second CSC block is placed at the back of the CP

section. Each CSC enables YPrPb-to-RGB and RGB-to-YCrCb

conversions. Many other standards of color space can be imple-

mented using the color space converters.

The CP block is available only for video signals with resolution

up to 1080p Deep Color (pixel rates up to 170 MHz). For resolu-

tions higher than 1080p, the video signal bypasses the CP block

and is routed directly to the pixel bus output as two 24-bit (4:4:4)

buses running at up to 150 MHz.

CP features include

•

Support for 525i, 625i, 525p, 625p, 720p, 1080i, 1080p,

and many other HDTV formats

•

Manual adjustments including gain (contrast), offset

(brightness), hue, and saturation

•

Free-run output mode that provides stable timing when

no video input is present

•

170 MHz conversion rate, which supports RGB input

resolutions up to 1600 × 1200 at 60 Hz

•

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

•

Data enable (DE) output signal supplied for direct

connection to HDMI/DVI transmitter

OTHER FEATURES

The ADV7619 has HS, VS, FIELD, and DE output signals with

programmable position, polarity, and width.

The ADV7619 has two programmable interrupt request output

pins: INT1 and INT2 (INT2 is accessible via one of the following

pins: MCLK/INT2, SCLK/INT2, or HPA_A/INT2). The ADV7619

also features a low power power-down mode.

The main I2C address can be set to 0x98 or 0x9A. On power-up or

after a reset, the I2C address is set to 0x98 by default. The address

can be changed to 0x9A by pulling up the VS/FIELD/ALSB pin

and issuing the I2C command SAMPLE_ALSB. For more infor-

mation, see the Register Access and Serial Ports Description

section in the UG-237.

The ADV7619 is provided in a 128-lead, 14 mm × 14 mm,

RoHS-compliant TQFP_EP package and is specified over the

0°C to 70°C temperature range.
