GENERAL DESCRIPTION The AD9389 is an 80 MHz high-definition multimedia inter- face (HDMI 1.1) transmitter. It supports HDTV formats up to 1080i and 720p, and graphic resolutions up to XGA (1024 × 768 @ 75 Hz). With the inclusion of HDCP, the AD9389 allows the secure transmission of protected content as specified by the HDCP 1.1 protocol. The AD9389 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 (linear pulse code modulation) audio or compressed audio including Dolby® Digital, DTS®, and THX®. The AD9389 helps to reduce system design complexity and cost by incorporating such features as HDCP master, I2C master for EDID reading, a single 1.8 V power supply, and 5 V tolerance on I2C and hot plug detect pins. Fabricated in an advanced CMOS process, the AD9389 is pro- vided in a space-saving, 80-lead, surface-mount, Pb-free plastic LQFP and is specified over the 0°C to 70°C temperature range. EVALUATION KITS AND OTHER RESOURCES Evaluation kits, reference design schematics, software quick start guide, and codes are available from the Analog Devices local sales and marketing personnel. |
