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 I
high fidelity, 8-channel I
surround audio at 192 kHz. The S/PDIF can carry stereo linear

Personal media players
DVD players and recorders
Digital set-top boxes
A/V receivers
HDMI repeaters/splitters
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
I
reading, a single 1.8 V power supply, and 5 V tolerance on the
I
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.
