GENERAL DESCRIPTION
The AD9889 is an 80 MHz, high-definition multimedia inter-
face (HDMITM 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 AD9889 allows
the secure transmission of protected content as specified by the
HDCP 1.1 protocol.
The AD9889 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 AD9889 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 AD9889 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.
