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. |
