【Abstract】 The signal integrity issue is very important in the design of high-speed communication devices. This paper addresses some signal integrity problems encountered during the design of a layer-3 switch, such as the noise of power distribution system, clock jitter, propagation delay and impedance of transmission line. The techniques are summarized for solving these problems.更多还原
