FEATURES
Low power HDMI/DVI transmitter ideal for portable
applications
Single 1.8 V power supply Video/audio inputs accept logic levels from 1.8 V to 3.3 V Digital video
80 MHz operation supports all HDTV resolutions from
Programmable 2-way color space converter Supports RGB, YCbCr, and DDR Supports ITU656-based embedded syncs Automatic input video format timing detection (CEA-861D) Digital audio Supports standard S/PDIF for stereo LPCM or compressed audio up to 192 kHz 8-channel, uncompressed LPCM I 2S audio up to 192 kHz Special features for easy system design On-chip MPU with I2C master to perform HDCP operations and EDID reading operations
5 V tolerant I2C and HPD I/Os, no extra device needed
No audio master clock needed for supporting S/PDIF and I2S On-chip MPU reports HDMI events through interrupts and registers 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) opera- tions, an I 2C® master for extended display identification data (EDID) reading, a single 1.8 V power supply, and 5 V tolerance on the I 2C and hot plug detect pins. For additional information and resources, see the Applications Information secti on. Fa bricated 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.
