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 -25C to +90C operation.
