GENERAL DESCRIPTION
S _{The AD9889 is an 80 MHz, high-definition multimedia inter-}
face (HDMI^TM 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
B _{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.

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.
