GENERAL DESCRIPTION
The AD9889A-BBCZ is an 80 MHz, high definition multimedia
interface (HDMI) v.1.2a transmitter. It supports HDTV formats
up to 720p/1080i, and computer graphic resolutions up to XGA
(1024 × 768 @ 75 Hz). With the inclusion of HDCP, the AD9889A
allows the secure transmission of protected content as specified
by the HDCP v1.1 protocol.
The AD9889A 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

The AD9889A helps to reduce system design complexity and
cost by incorporating such features as an internal MPU for
HDCP operations, an 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 AD9889A
is available in a space saving, 76-ball, CSP_BGA surface-
mount package. The CSP_BGA package is specified from
−25°C to +90°C.
