GENERAL DESCRIPTION
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 at 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.
