GENERAL DESCRIPTION
The AD9397 is a digital visual interface (DVI) receiver
integrated on a single chip. Also included is support for high
bandwidth digital content protection (HDCP) with internal key
storage.
video content. The AD9397 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.
The AD9397 contains a DVI 1.0-compatible receiver and
supports all HDTV formats (up to 1080p and 720p) and display
resolutions up to SXGA (1280 × 1024 @ 80 Hz). The receiver
features an intrapair skew tolerance of up to one full clock cycle.
With the inclusion of HDCP, displays can receive encrypted
Fabricated in an advanced CMOS process, the AD9397 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.
