GENERAL DESCRIPTION

The AD9389B 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 @ 60 Hz). With the inclusion of HDCP, the AD9389B allows

the secure transmission of protected content as specified by the

HDCP v. 1.2 protocol.

Figure 1.

The AD9389B supports both S/PDIF and 8-channel I

S audio.

Its high fidelity, 8-channel I

S 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 AD9389B helps reduce system design complexity and cost

by incorporating such features as an internal MPU for HDCP

operations, an I

C master for EDID reading, a single 1.8 V power

supply, and 5 V tolerance on the I

C and hot plug detect pins.

Fabricated in an advanced CMOS process, the AD9389B is

available in a space-saving, 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.
