AD9888 is an analog flat panel interface chip produced by Analog Devices. It has a sampling rate of 100/140/170/205 MSPS. Its features include a maximum sampling rate of 205 MSPS, a programmable analog bandwidth of 500 MHz, an analog input range of 0.5 V to 1.0 V, a PLL clock jitter of less than 450 ps p-p, a 3.3 V power supply, full synchronization processing, hot plug detection, 2:1 analog input multiplexer, 4:2:2 output format mode, midscale clamping, and low power consumption.
The AD9888 is a complete 8‑bit, 205 MSPS monolithic analog interface optimized for capturing RGB graphics signals from PCs and workstations. It integrates analog inputs, a PLL‑generated pixel clock, programmable gain, offset, and clamp control, and delivers three‑state CMOS outputs.
Key features include a 500 MHz full‑power analog bandwidth, low power consumption (<1 W typical at 205 MSPS), 2‑wire serial configuration, and a 128‑lead MQFP surface‑mount package. The datasheet details electrical characteristics, pin configurations, and design guidelines for flat‑panel display applications.
