Abstract: An integrated circuit is provided. The integrated circuit includes a control circuitry, a plurality of pins, and a plurality of driving units coupled to the pins. The control circuitry provides a plurality of control signals according to data to be transmitted. The pins are coupled to a device via a plurality of conductive traces of a printed circuit board (PCB). The control signals control each of the driving units to selectively provide the data or one specific shielding pattern via the corresponding pin and the corresponding conductive trace of PCB to the device.

Abstract: An electronic apparatus is provided. The electronic apparatus includes a printed circuit board (PCB) with a first signal path and a second signal path therein, a first finger disposed on the first signal path, a second finger disposed on the second signal path, a controller disposed on the PCB and coupled to a first memory via the first finger and to a second memory via the second finger, and a damping device disposed on the second signal path. The first and second signal paths share a common segment between the controller and a branch point on the PCB. The damping device is disposed between the second finger and the branch point. The distance between the first finger and the branch point within the first signal path is smaller than the distance between the second finger and the branch point within the second signal path.
