GENERAL DESCRIPTION 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 HDCP, the ADV7520 allows the secure transmission of protected content, as specified by the HDCP 1.3 protocol. The ADV7520 supports x.v.Color™ (Gamut Metadata) for a wider color gamut. 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 features such 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 ADV7520 is available in a space saving, 64-lead LFCSP. The package is RoHS compliant and is specified for −25°C to +85°C operation. |
