Design and realisation of a broadband switch for 70 Mb/s communications

Describes an experimental 70 Mb/s data switch implemented in CMOS technology. This is based entirely on space switching, and has common clocks, with signal retiming in each block. Local control is suggested as type 8051 microprocessors, supplemented by 16 bit or 32 bit microprocessors. The use of short distance stripline technology and of 17-layer printed circuits is proposed. Block diagrams are presented.
