Integrated circuit of matrix switch

Abstract

Abstract PURPOSE:To sharply reduce crosstalks at a high frequency in a matrix switch integrated circuit of (nXn) channels arrayed on an IC, by arraying matrix switches in (nXn/2)X2. CONSTITUTION:The matrix switch integrated circuit of this invention is composed of (nXn) pieces of switch cells (1-1, 1-2-1-n), (2-1, 2-2-2-n), (n-1, n-2-n-n) and (n) pieces of output buffers 3-1, 3-2-3-n. Since the matrix switch integrated circuit is formed in such a way, the wiring intersection is eliminated on the output side and remains on the input side only. As a result, crosstalks at a high frequency can be reduced sharply.
