Patent ID: 7167936

Claim:
High-speed line card for a switchgear cabinet having: (a) at least one plug for connection to the switchgear cabinet; (b) at least one circuit for the high-speed data processing of data, which circuit is arranged on the line card and is integrated in a housing; (c) the integrated circuit having at least one parallel interface provided at a housing side for receiving data from the plug via a bus and at least parallel interface provided at a further housing side for outputting data to a parallel/serial converter via a bus; (d) the buses each having a plurality of bus lines running parallel to an edge of the line card for the transmission of data with a data transmission rate of more than one gigabit per second, wherein each bus line has a bend having a bend angle and the bend angle is dependent on an inclination angle of the housing sides of the integrated circuit with respect to the edge of the line card, and (e) the housing sides of the integrated circuit, for the purpose of minimizing the propagation time differences between the data signals transmitted on the bus lines, being oriented at an inclination at a specific angle with respect to the edge of the line card.
