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 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.
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
