Patent ID: 7175476

Claim:
A modular jack having a crosstalk canceling pattern for high-speed communications, the modular jack comprising a plurality of insert pins electrically connected to a modular plug, a plurality of IDC terminals connected to an UTP cable, a printed circuit board connecting the insert pins to the IDC terminals via a transmission line, and a first compensating capacitor provided on a transmission line of the printed circuit board to compensate for first parasitic capacitance generated between the insert pins, wherein first parasitic inductance generated in the insert pins and a transmission line between the insert pins and the first compensating capacitor, and second parasitic inductance generated in a transmission line between the first compensating capacitor and the IDC terminals are symmetrical with respect to the first compensating capacitor; and a second compensating capacitor, generating second compensating capacitance, is provided in a transmission line adjacent to the IDC terminals so as to correct phase mismatch, due to an increase in capacitance caused by the first compensating capacitor and an increase in the first and second parasitic inductance.
