S _{GENERAL DESCRIPTION}
The AD9389 is an 80 MHz high-definition multimedia inter-
face (HDMI 1.1) transmitter. It supports HDTV formats up to
B _{1080i and 720p, and graphic resolutions up to XGA (1024 × 768}
@ 75 Hz). With the inclusion of HDCP, the AD9389 allows the
secure transmission of protected content as specified by the
O ^{HDCP 1.1 protocol.}

The AD9389 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 AD9389 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.
The AD9389 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®.
