Abstract:
1. An interface device for connecting a transmitting device having a first plurality of terminals and deriving a plurality of signals of a predetermined data pattern, the signals being arranged in groups, and a receiving device having a second plurality of terminals for receiving said signals; the interface device comprising: input connectors connectable to said transmitter's terminals and output connectors connectable to said receiver's terminals; a plurality of transmission lines within said interface device, for interconnecting said input and output connectors, the transmission lines being arranged in groups corresponding to said groups of signals; and a nonvolatile memory for storing data on timing errors in each said group of transmission lines, measured with respect to a reference signal where a tester is running a specific data pattern, to provide compensation of the timing errors caused by crosstalk effects for this particular combination of signals; so that the transmitting device is capable of compensating for timing errors in said groups of transmission lines using data read from said nonvolatile memory.
