Abstract :
The integrity analysis of the PCB signal has already become important due to the use of high-speed clock, high-speed signal transmitter, high definition and high-speed spare part. In the high speed board/package design, designers are trying to improve or minimize all the impedance mismatches along the high speed signal path. Impedance discontinuities on PCB board will cause signal reflections, degrade the high-speed signal slew rate and eye height. In this paper, signal integrity of differential signal improvement analysis method is proposed. We analyze the correlation of channel width, spacing, and impedance. Then we observe that can increase the odd mode effect by decreasing the spacing. By the way, we not only can enhance the slew rate performance, but can also save more area of routing.
