LCoS微显的视频解码芯片配置方法设计
Configuration Design of the Video Decoder Chip for the LCoS Micro-display
摘要
AD9883是一款全8位,转换速率最高可达140 MSPS的A/D转换芯片,300 MHz的模拟带宽支持转换图像的分辨率可达SXGA(1 280×1 024@75 Hz),因此在RGB图像处理、LCD监视器、平板显示以及微显示领域都得到了广泛应用。采用有限状态机(Finite state machine,FSM)的方法,基于VerilogHDL模拟I2C通信协议对AD9883进行初始化配置,使其能够适用于LCoS微显示控制电路的A/D转换要求。
Abstract
The AD9883 is a complete 8-bit monolithic analog interface with 140 MSPS conversion speed. Its full power analog bandwidth of 300 MHz supports resolutions up to SXGA (1 280×1 024@75 Hz), which has been widely applied in RGB graphics processing, LCD monitors projectors, plasma display panels, LCoS microdisplays and so on. The I2C bus configuration of the AD9883 is initialized by FSM based on VerilogHDL, so that it can be used in the LCoS microdisplay control circuit to meet the conversion requirements.
