The AD9889B series high-performance HDMI/DVI Transmitter supports HDTV formats up to 1080p and computer graphic resolutions up to UXGA (1600 x 1200 at 60Hz). With the inclusion of HDCP, it allows the secure transmission of protected content as specified by the HDCP v. 1.2 protocol. It 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 192kHz. The S/PDIF can carry stereo LPCM audio or compressed audio, including DTS?, THX? and Dolby? Digital. It 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 1.8V power supply and 5V tolerance on the I2C and hot plug detect pins. It is fabricated in an advanced CMOS process.
