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.

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

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.

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.
