DEVICE FOR SHIELDING TRANSMISSION LINE FROM GROUND OR POWER SUPPLY

摘要

PROBLEM TO BE SOLVED: To provide an integrated circuit provided with a set of contacts for connecting the integrated circuit to a differential transmission line.

SOLUTION: The set of contacts comprises at least one first pair of contacts intended to receive a first power supply voltage, a second pair of contacts intended to receive a second power supply voltage and a third pair of contacts, referred to as signal contacts, intended to be connected to the differential transmission line. A power supply contact may receive either a ground level voltage or one of the high or low power supply voltages, forming two positive or negative power supply configurations. The signal contacts are surrounded by the power supply contacts to accomplish a shielding effect which is independent of the positive or negative power supply configurations.
