ASIC1810 RGB 逐行扫描专用芯片
视频 ADC 芯片，R、G、B 3CHANNEL， 每 CHANNEL 有 2 个 1K*8bit SRAM，
SRAM WRITE CYCLE TIME 64nS，SRAM READ CYCLE TIME 32nS。每行采 样 1000
个像素点，两个 SRAM 交替读写，当把第 N 行像素点数据写入一个 SRAM,同时从另一
个 SRAM 中把第 N-1 行数据读出，读完一次，再读一次，一共读俩次，每行读周期 30uS，
有 2uS 的回程时间；每行写周期 64uS。
RIN、GIN、BIN 行同步频率 15KHZ，图像时间为 53uS，回程时间 11uS; 经 ASIC
后， ROUT、GOUT、BOUT 行同步频率 30KHZ，回程时间 2uS。
