ADV7520NK allows the secure transmission of protected
content as specified by the HDCP v1.3 protocol.
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 LPCM audio or compressed audio including Dolby®
Digital and DTS®.
The ADV7520NK helps to reduce system design complexity
and cost by incorporating such features as an internal MPU for
HDCP operations, an I2C master for EDID reading, a single
1.8V power supply and 5 V tolerance on I2C and hot plug detect
pins.
Fabricated in an advanced CMOS process, the ADV7520NK
is available in a space saving, 76-ball, CSP_BGA or 64-lead
LFCSP surface-mount package. Both packages are available as
RoHS compliant and are specified from −25°C to +85°C
operational.
