The AD9387NK is an 80 MHz, high definition multimedia interface (HDMI®) v.1.3 transmitter. 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 AD9387NK allows the secure transmission of protected content, as specified by the HDCP 1.3 protocol.The AD9387NK 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 AD9387NK 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 AD9387NK is available in a space saving, 76-ball CSP_BGA. The package is RoHS compliant and is specified from −25°C to +90°C operation.APPLICATIONSDigital video camerasDigital still camerasPersonal media playersCellular handsetsDVD players and recordersDigital set-top boxesA/V receiversHDMI repeater/splitter
