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.
GENERAL DESCRIPTION
The AD9389 is an 80 MHz high-definition multimedia inter-
face (HDMI 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 AD9389 allows the
secure transmission of protected content as specified by the
HDCP 1.1 protocol.
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®.
