摘要：A high speed video switch in a KVM system using discrete Radio Frequency (RF)switch circuits. The RF switch circuits are configured into a multiplexed circuit to routevideo signals from a selected host computer to a target monitor. Voltage converters areused to provide control signals of the proper voltage to the RF switch circuits. Peaking
operational amplifiers are used to compensate for the roll-off effect caused by the videoconnectors. An On Screen Display (OSD) switch using the RF switches is used to rapidlyswitch between the OSD data and host computer video for display to the target operatorcontrol center monitor.
