Compensation of unbalanced capacitive crosstalk noise in category-5E modular jack using balancing capacitor in PCB

摘要

We have successfully designed a PCB substrate with the embedded balancing capacitors for the category-5E modular jack to compensate the unbalanced capacitive crosstalk noise. The NEXT (near-end crosstalk) after the crosstalk compensation is below -45 dB at 100 MHz.
