Dual, 500MHz Triple, Multiplexing Amplifier Evaluation Boards


The ISL5948xEVAL1Z evaluation boards contain the ISL59481, ISL59482 or ISL59483 dual 4:1 RGB MUX amp and associated components needed to implement an 8:1 RGB+H/V sync video multiplexer. The 8 video input ports, and single output port are accessed using standard 15 pin VGA female connectors. The I/O connectors are compatible with most VGA, SVGA and XGA video sources and video monitors with VGA cable interfaces. A typical application would use the ISL5948xEVAL1Z board to multiplex anywhere from 2 to 8 PC’s or laptops to a single video monitor or projector.
