The ADV7520NK is an 80 MHz, high definition multimedia
interface (HDMI™) v.1.3 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 ADV7520NK allows
the secure transmission of protected content, as specified by the
HDCP 1.3 protocol.

HDCP AND EDID
The ADV7520NK 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 ADV7520NK helps reduce system design complexity and
cost by incorporating such features 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 ADV7520NK
is available in a space saving, 76-ball CSP_BGA. The package is
RoHS compliant and is specified for −25°C to +90°C operation.
