In this talk, signal and power integrity (SI/PI) of the mobile high definition link (MHL) system, having discontinuous and asymmetric structures have been analyzed. In the SI/PI analysis of the MHL system, three dimensional (3D) electromagnetic (EM) solver and time domain reflectometry (TDR) method are carried out. As a result, the differential signals with the discontinuous reference plane experience the degeneration of transmission characteristics due to the impedance mismatch at the discontinuities in return current path of the signals. Moreover, it is found that the SI/PI characteristics of the differential signal could be significantly degenerated, when the asymmetric guard traces with ground via holes for electromagnetic interference (EMI) reduction are located closer to the signal trace than the balanced reference plane. Therefore, SI/PI can be guaranteed with widely open eye diagram using the symmetric and continuous reference plane for the coupled signal lines in the high-speed digital interconnect. Also, wideband power plane isolation technique will be presented for enhanced power integrity. For the analysis of the quite complicated overall system, divide-and-conquer strategy has been successfully demon
