Hi, Experts In the last thread,Michael said "Placing them at the RX side generally helps to minimize impact of the impedance discontinuity given the degradation of edge rate from dispersion" Does place the AC capacitor near the receiver really help SI? Which is the better place for placing the decoupling capacitor, near the transmitter or near the receiver? How to choose the value of the decoupling capacitor? it is based on the data rate, code style or other things? can we calculate it manually? Thanks.
