Abstract
Disclosed herein are a crosstalk canceling pattern for high-speed communications and a modular jack having the same, which includes a compensating capacitor on a transmission line to cancel crosstalk due to parasitic capacitance generated between neighboring insert pins, and includes a second compensating capacitor to correct phase mismatch due to parasitic inductance generated in insert pins and transmission lines, when a high-frequency signal is applied. The modular jack having the crosstalk canceling pattern for high-speed communications includes a housing, a printed circuit board, a lower contact block, and an upper contact block. The hosing includes a plug insert hole, an insert pin locking plate, and a coupling guide part. The printed circuit board is a multi-layered structure having a plurality of compensating capacitors. The lower contact block is mounted to the lower surface of the printed circuit board. The upper contact block is mounted to the upper portion of the lower contact block, and divides UTP cable wires to be connected to IDC terminals.
