THEORY OF OPERATION

HDMI RECEIVER

The HDMI receiver supports HDTV formats of up to 1080p.

The HDMI-compatible receiver on the ADV7613 allows active

equalization of the HDMI data signals. This equalization

compensates 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 20 meters to achieve robust

receiver performance.

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 the following:

•

LPCM (uncompressed audio)

•

IEC 61937 (compressed audio)

•

DSD audio (1-bit audio)

•

HBR audio (high bit rate compressed audio)

•

Audio sample, HBR, DSD packet support

•

Support for EDID RAM

There is no Deep Color support in the ADV7613.

HDCP REPEATER FUNCTIONALITY

With the inclusion of HDCP, displays can receive encrypted

video content. The HDMI interface of the ADV7613 allows

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 specification.

COMPONENT PROCESSOR (CP)

The ADV7613 has two any to any, 3 × 3 color space conversion

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

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

CP section. Each CSC enables YCrCb to RGB and RGB to

YCrCb conversions.

CP features include

•

Support for 525p, 625p, 720p, 1080p, as well as some

graphics standard (WVGA, WXGA)

•

Manual adjustments including gain (contrast), offset

(brightness), hue, and saturation

•

Free run output mode that provides stable timing when no

video input is present

•

Standard identification enabled by the STDI block

LVDS TRANSMITTER FEATURES

The LVDS encoder can package data into 6-bit or 8-bit non-dc

balanced OpenLDI mapping or 8-bit VESA mapping. The

ADV7613 can output 24-bit OpenLDI data over two LVDS

transmitters up to a maximum input resolution of 1080p at 60 Hz.

The two LVDS output ports (Port 1 and Port 2) can drive two

LVDS display panels with video streams from a single video

data stream received by the HDMI receiver. The HDMI receiver

splits the single video stream into two video streams: the odd

video stream and the even video stream. LVDS Output Port 1

outputs the odd video stream. LVDS Output Port 2 outputs the

even video stream.

The maximum video resolution supported by a single LVDS

output port must have a clock frequency of 92 MHz or less.

interface.

OTHER FEATURES

Other features of the ADV7613 include the following:

•

Programmable interrupt output pin, INT

•

Chip select, CS

AUDIO OUTPUT DATA

The audio output pins (AP0 to AP5) can output audio data in a

number of formats as described in Table 6.
