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.
