Abstract
A crosspoint analog data selector for coupling data received on a predetened number of input channel lines onto a predetermined lesser number of output channel lines. The crosspoint analog data selector includes a selector section and a control section. The selector section includes two or more crosspoint switch sections, each crosspoint switch section including a predetermined number of input terminals and a predetermined number of output terminals. Each output terminal is individually energizable. Each input terminal is connected to a different input channel line, such that none of the input channel lines are connected to input terminals of multiple crosspoint switch sections. Each output terminal is connected to one of the output channel lines such that each output channel line is connected to an output terminal of each of the crosspoint switch sections. The control section is responsive to commands to enable the selector section to couple data from a selected input channel line to a selected output channel line. In that operation, the control section (i) initially enables the crosspoint switch sections to de-energize their output terminals connected to the selected output channel line, (ii) enables the crosspoint switch section connected to the selected input channel line to connect its input terminal connected thereto to its output terminal connected to the selected output channel line, and (iii) enables the crosspoint switch section connected to the selected input channel line to energize its output terminal connected to the selected output channel line.
