Abstract:
1. A crosspoint switch architecture having: a monolithic substrate; a plurality (N) of electrical inputs provided on said substrate; a plurality (M) of electrical outputs provided on said substrate; switch means disposed on said substrate for selectively interconnecting said inputs to said outputs, said switch means having M multiplexers and a plurality (N) switchable amplifiers, each of said switchable amplifier operatively coupled to a corresponding one of said N inputs; and means disposed on said substrate for controlling said switch means, wherein each multiplexer includes N selection multiplexers, wherein each of said N inputs to each of said multiplexer is received through a respective one of said N switchable amplifiers, and wherein one of the N inputs can be selected for outputting to one of the M outputs by switching on the corresponding switchable amplifiers and disabling the rest of the switchable amplifiers.
