Advanced architecture for a one-chip 16×16 digital switch

A one-chip 16×16 digital switch (SWEL) is presented which is designed for use in a wide variety of applications, ranging from digital mobile radio and satellite applications, to PCM switching systems (integrated services digital network). It provides a compact, low-power solution to perform in channel-controlled switching of 64-kb/s or 2-Mb/s channels. Both architecture and design issues are discussed in detail; a 1.2 μm double metal CMOS technology was employed in the design. The multiplexed architecture allows for easy implementation of new application-specific requirements, making this circuit the cornerstone for new telecommunication switching products
