Patent ID: 8013659

Claim:
A distributed signal multiplexer circuit to programmably route electronic signals, comprising: a first distributor subcircuit, including an input port, an output port, a switch, and a control port, configured to connect the input port to the output port through the switch, a state of the switch being controlled by information received at the control port, the first distributor subcircuit being part of a first power domain defined by a first voltage source; a second distributor subcircuit, including an input port, an output port, a switch, and a control port, configured to connect the input port to the output port through the switch, a state of the switch being controlled by information received at the control port, the second distributor subcircuit being part of a second power domain defined by a second voltage source different from the first voltage source; and an aggregator subcircuit, including a first input port, a second input port, an output port providing an output port signal, and a selector device, configured to have the first input port communicatively coupled with the output port of the first distributor subcircuit, the second input port coupled with the output port of the second distributor subcircuit, and the output port signal being a signal selected from among the signals received at the input port of the first distributor subcircuit and the input port of the second distributor subcircuit.
