This reference design (RD) features a fully assembled and tested surface-mount printed circuit board (PCB). The RD board utilizes the MAX4885 1:2 or 2:1 multiplexer and other ICs to implement a complete video graphics array (VGA) 8:1 multiplexer. VGA input/output connections are provided to easily interface the MAX4885 RD board with VGAcompatible devices. The RD board gives the option to use a single 5V DC power supply (V+), or this RD board can be powered from any one of the eight VGA sources.
