Abstract
The cross-point chip discussed in this distribution was designed for use in an experimental TV-distribution network. Such a network has to be non-blocking and therefore requires a considerable amount of hardware, which is typically proportional to the product of the numbers of programs and the number of subscribers. The special architecture, this chip was designed for, reduces this hardware by factor of two while introducing conditional blockings into the network, which can be resolved by path-rearrangement. This feature has to be realized within the crosspoint-chips, therefore increasing their complexity, because synchronous signal-processing is required. On the other hand, the ability of synchronizing broadband-signals can be used for the implementation of a self-test.
