The AD9882A is a high-performance, dual interface solution that combines low system cost and excellent image quality with reliable operation. The design of the AD9882A is optimized to meet the needs of XGA and SXGA displays without compromising image quality. The AD9882A offers designers the flexibility of an analog interface and a Digital Visual Interface (DVI) receiver integrated together on a single chip. Also included is support for High-bandwidth Digital Content Protection (HDCP).
Analog Interface
The AD9882A is a complete 8-bit, 140 MSPS monolithic analog interface optimized for capturing RGB graphics signals from personal computers and workstations. Its 140 MSPS encode rate capability and full-power analog bandwidth of 300 MHz supports resolutions up to SXGA (1280 x 1024 at 75 Hz).
Digital Interface
The AD9882A contains a DVI 1.0 compatible receiver and supports display resolutions up to SXGA (1280 x 1024 at 60 Hz). The receiver operates with true color (24 bit) panels and also 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 AD9882A allows for authentication of a video receiver, decryption of encoded data at the receiver and renew-ability of that authentication during transmission as specified by the HDCP v1.0 protocol.
Fabricated in an advanced CMOS process, the AD9882A is provided in a space-saving 100-lead LQFP surface mount plastic package and is specified over the 0°C to +70°C temperature range.
