The AD9889B is a 165 MHz, high definition multimedia inter-face (HDMI®) v. 1.3 transmitter. It supports HDTV formats up to 1080p, and computer graphic resolutions up to UXGA (1600 × 1200 @ 60 Hz). With the inclusion of HDCP, the AD9889B allows the secure transmission of protected content as specified by the HDCP v. 1.2 protocol. The AD9889B 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 audio or compressed audio, including DTS®, THX®, and Dolby® Digital. The AD9889B helps reduce system design complexity and cost by incorporating such features as an internal MPU for HDCP operations, an I2C master for EDID reading, a single 1.8 V power supply, and 5 V tolerance on the I2C and hot plug detect pins. Fabricated in an advanced CMOS process, the AD9889B is available in a space-saving, 76-ball CSP_BGA or 64-lead LFCSP surface-mount package, and an 80-lead LQFP surface-mount package. All packages are available as Pb-free and are specified from ?25°C to +85°C.
