AD9888KS-140

GENERAL DESCRIPTION

The AD9888 is a complete 8-bit, 205 MSPS monolithic analog interface optimized for capturing RGB graphics signals from personal computers and workstations. Its 205 MSPS encode rate capability and full-power analog bandwidth of 500 MHz supports resolutions up to UXGA (1600 × 1200 at 75 Hz). For ease of design and to minimize cost, the AD9888 is a fully integrated interface solution for flat panel displays. The AD9888 includes an analog interface with a 205 MHz triple ADC with internal 1.25 V reference, PLL to generate a pixel clock from HSYNC and COAST, midscale clamping, and programmable gain, offset, and clamp control. The user provides only a 3.3 V power supply, analog input, and HSYNC and COAST signals. Three-state CMOS outputs may be powered from 2.5 V to 3.3 V.
