GENERAL DESCRIPTION
The AD9389A-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 AD9389A
allows the secure transmission of protected content as specified
by the HDCP v1.1 protocol.
2
The AD9389A supports both S/PDIF and 8-channel I
2
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
