Overview
The AD9888KS-170, produced by Analog Devices Inc., is a complete 8-bit, 170 MSPS (mega-samples per second) monolithic analog interface. It is optimized for capturing RGB graphics signals from personal computers and workstations. This device supports resolutions up to 1600 × 1200 (UXGA) at 75 Hz, making it suitable for high-resolution display applications. The AD9888KS-170 is a fully integrated interface solution for flat panel displays, designed to ease the design process and minimize costs.
