Overview
The AD9883AKST-110, produced by Analog Devices Inc., is a highly integrated 8-bit, 140 MSPS monolithic analog interface. This device is optimized for capturing RGB graphics signals from personal computers and workstations. It features a maximum conversion rate of 140 MSPS and a full-power analog bandwidth of 300 MHz, supporting resolutions up to SXGA (1280 x 1024 at 75 Hz). The AD9883A is implemented in a high-performance CMOS process and includes all necessary input buffering, signal DC restoration (clamping), offset and gain (brightness and contrast) adjustment, pixel clock generation, sampling phase control, and output data formatting. All controls are programmable via a 2-wire serial interface.
