Abstract :
In data transmission equipment for a broadband system, high-speed serial signal transmission has become essential technology. In order to transmit high-speed serial signals with low bit-error-rate, high accuracy in impedance matching of the transmission path is needed. In this paper, first we clarify the relation between the impedance deviations of each part in a signal transmission path and the return loss of this path by analyzing a simple equivalent circuit. Next, an optimization technique for the signal path between a PCB and a FC-BGA package is proposed. The simulation results show that the reflection loss is less than -13 dB and that the insertion loss is less than 2 dB ranging from DC to 16 GHz.
