Abstract:
An apparatus for selectively routing a plurality of input signals to M output terminals, where M is an integer greater than three, the apparatus comprising:N crosspoint switch arrays, wherein N is an integer greater than one, wherein each crosspoint switch array has M output lines, wherein each crosspoint switch array selectively routes a separate subset of said input signals to its M output lines; and M output buffers, wherein for all values of K from one through M, each Kth output buffer actively buffers each input signal routed to a Kth output line of any one of the crosspoint switch arrays onto a Kth one of said M output terminals, and each Kth output buffer comprises an OR gate having inputs linked to a Kth output line of each crosspoint switch array and driving the Kth one of said output terminals.
