GENERAL DESCRIPTION
The AD9381 offers a high definition multimedia interface
(HDMI) receiver integrated on a single chip. Also included is
support for high bandwidth digital content protection (HDCP)
via an internal key storage.
The AD9381 contains an HDMI 1.0-compatible receiver and
supports all HDTV formats (up to 1080p) and display
resolutions up to SXGA (1280×1024 @ 75 Hz). The receiver
features an intrapair skew tolerance of up to one full clock cycle.
With the inclusion of HDCP, displays may now receive
encrypted video content. The AD9381 allows for authentication
of a video receiver, decryption of encoded data at the receiver,
and renewability of that authentication during transmission as
specified by the HDCP 1.1 protocol.
