GENERAL DESCRIPTION
The AD9398 offers a high definition multimedia interface
(HDMI) receiver integrated on a single chip. Also included is
support for high bandwidth digital content protection (HDCP).
The AD9398 contains a HDMI 1.0-compatible receiver and
supports all HDTV formats (up to 1080p) and display resolu-
tions 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 can now receive encrypted
video content. The AD9398 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.
Fabricated in an advanced CMOS process, the AD9398 is
provided in a space-saving 100-lead, surface-mount, Pb-free,
plastic LQFP and is specified over the 0°C to 70°C temperature
range.
