    摘要： A crosspoint LSI adapted to an exchanger in ISDN, for transmission of asynchronous transfer mode (ATM) cells in communication is provided. The crosspoint switching LSI includes many unit switch cells arranged in rows and columns. When a unit switch cell is turned on, the unit switch cell responds to a differential data signal on an input data line to drive differentially an output data line pair. The unit switch cells operate differentially so that the data signals of the ATM cells are transmitted, which improves a signal transmission rate.

    摘要： A crosspoint matrix has matrix input lines which lead via pairs of switching elements to matrix output lines having, respectively, two signal conductors which are respectively connectible to a reference potential source via a precharging transistor controlled by a precharging clock and which have signal inputs of differential amplifier with a trigger behavior connectible thereto. The pair of switching elements respectively comprise two input transistors that have their control electrodes connected to a signal conductor of the appertaining matrix input line and form a series circuit with a respective switching transistor leading to the one or, respectively, other output signal conductor, a logic element that is respectively oppositely controlled by the precharging clock is inserted into the input lines and, in the switching elements, the ends of the series circuits facing away from the matrix output line are directly connected to the appertaining terminal of the operating voltage source.

    摘要： A laser programmable integrated circuit chip has a plurality of logic modules organized as rows and columns. The modules and other chip components are connected by a grid-like array of conductors. The conductors are initially unattached. Customization occurs by fusing laser diffuseable links and severing cut points on the conductors. The modules have continuous conductor lines running through them. These conductor lines aid in testing and are useful in routing and error avoidance. The chip also contains test registers to test the array of logic modules, the input/output blocks, and the conductors.
