Gaps In Return Planes – Bad News for EMI
Currently, there is an ongoing discussion among SI and EMC engineers on the fine points of PC board design for best signal integrity and EMI performance. Among the topics it seems designing in gaps or slits in ground return planes always comes up. Gaps can also occur mistakenly due to the addition of some connectors or other object that creates gaps in the copper. In fact, … [Read more...]
T-Filters, Transmission Lines and EMC
Have you ever had a signal integrity issue that did not have its toll on EMC? If you did then you should consider yourself lucky to have avoided this nightmare. I. Situation: An I2S bus master clock driver is set to 12.288MHz and run at 3.3V. Drive strength is at 50-Ohms. Rise time is at 2ns. Fall time is at 2ns. The driver is located on the “master board” and the bus … [Read more...]
Interference Technology’s Top Ten Articles From 2005 to 2016
