Abstract

A single in-line package with several differential line drivers 1 and receivers 2 is described for use in high-speed test equipment. Drivers 1 and receivers 2 are positioned on the first connector 3 of a cable 4 linking a first module 5 to a second module 6 of high- speed test equipment. Similarly, receivers 2 and drivers 1 are positioned on the second connector 7 of cable 4. As in high-speed test equipment, fast signals have to be transmitted differentially; in order to maintain the required speed and noise margin, differential line drivers 1 and receivers 2 are required on the two modules 5 and 6. This means that each signal occupies two I/O pins on both modules 5 and 6.
