GENERAL DESCRIPTION
The ADV7520 is an 80 MHz, High-Definition Multimedia
Interface (HDMI™) transmitter with consumer electronic
control (CEC). It supports HDTV formats up to 720p and 1080i
and computer graphic resolutions up to XGA (1024 × 768 @
75 Hz). With the inclusion of HDCP, the ADV7520 allows the
secure transmission of protected content, as specified by the
HDCP 1.3 protocol.
The ADV7520 supports x.v.Color™ (Gamut Metadata) for a
wider color gamut.
The ADV7520 supports both S/PDIF and 8-channel I2S audio. Its
high fidelity, 8-channel I2S can transmit either stereo or 7.1
surround audio at 192 kHz. The S/PDIF can carry stereo linear
pulse-code modulation (LPCM) audio or compressed audio,
including Dolby® Digital and DTS®.
The ADV7520 helps reduce system design complexity and cost
by incorporating features such as an internal microprocessor for
high-bandwidth digital content protection (HDCP) operations, an
I2C® master for extended display identification data (EDID)
reading, a single 1.8 V power supply, and 5 V tolerance on the
I2C and hot plug detect pins. For additional information and
resources, see the Applications Information section.
Fabricated in an advanced CMOS process, the ADV7520
is available in a space saving, 64-lead LFCSP. The package is RoHS
compliant and is specified for −25°C to +85°C operation.

TERMINOLOGY
480i, 480p, 576i, 576p, 720p, 1080i, 1080p
Common video modes—refer to EIA/CEA-861-D for more
information.
VGA, SVGA, XGA, SXGA, UXGA
Common graphics modes—refer to www.VESA.org for more
information.
CEC
Consumer electronics control is used to unify remotes of
differing make to perform a given task with one-button touch.
DDC
Display data channel is used to communicate between to the
source and sink to determine sink capabilities. It is also used as
the HDCP key communications channel.
DDR
Double data rate clocks capture data on both the rising and
falling edge of the clock.
EDID
Extended display identification is used to store monitor (sink)
capabilities in an EEPROM.
HBR
High bit rate audio is used to define sample rates greater
than 192 kB.
HDCP
High bandwidth digital content protection is a method of
protecting content from unauthorized digital copying.
HDMI
High-Definition Multimedia Interface is composed of three
TMDS differential data channels and one differential clock
channel. It is defined to include video streams up to 3.7 Gbps
as well as audio.
I2C
Inter-IC Communications is a Philips two-wire serial bus for
low speed (up to 400 kHz) data.
I2S
Inter-IC Sound is a serial Philips bus designed specifically
for audio.
LPCM
Linear pulse code modulation is a method of encoding audio
samples.
RGB
Red, green, blue is the standard definition for three-color
graphics and video.
TMDS
Transition minimized differential signaling is the format used
by the three data channels in HDMI. This encodes eight bits
into 10 bits and serializes them.
x.v.Color
This is feature of HDMI v.1.3 in which the color gamut can be
extended or altered beyond the normal range to accommodate a
given sink.
YCrCb
This is a common color format for video where the Y component
is luminance and the Cr and Cb signals are color difference
signals. 4:4:4 defines a Y, Cr, and Cb for each pixel; 4:2:2 defines
a Y for each pixel and a sharing of Cr and Cb between two
sequential pixels. In this manner, compression of 33% is possible.
