We're using the WEIM to talk to an FPGA, but also need to have a VGA display connected. So we need to change the pins used for output of the HSYNC and VSYNC external signals (the QSB and Linux driver are set up to use EIM_OE and EIM_RW as the HSYNC and VSYNC output pins, ...
该设备实现了一个完整的2:2双图形交叉解决方案的VGA信号交换。CXAS42254为RGB信号提供12个超高频700MHz SPST开关,为显示数据通道(DDC)信号提供4个低频钳位开关,为HSYNC和VSYNC信号提供2对电平移位缓冲器,还提供集成扩展ESD保护。CXAS42254用于从两个源中选择一个源到笔记本电脑中的两个目标。水...
