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 embedded HDCP keys, the ADV7520 allows the secure transmission of protected content, as specified by the HDCP 1.3 protocol.
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 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 I2 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 25C to +85C operation.
