ABSTRACT:
A digital radio frequency switch system and method, adapted to receive a plurality of inputs, generate a plurality of outputs, and simultaneously route a plurality of inputs to any of a plurality of outputs, comprising an array comprising a plurality of inputs, having a plurality of associated clocks; a digital control input adapted to receive a signal indicative of a mapping between at least one of said inputs and at least one respective output; a digital logic array, responsive to said digital control input for simultaneously communicating a plurality of signals each corresponding to one of the plurality of inputs and a respective associated clock to at least one of said outputs indicated by the digital control input; and an array of the outputs, each adapted to present a regenerated signal corresponding to one of the plurality of inputs and a respective associated synchronized regenerated clock maintaining accurate relative timing therebetween.
