Common Mode Choke Selection Common Mode Choke Selection Noise on power supply lines can be a major headache. We'll examine how to select a common-mode choke to help eliminate common-mode noise. Read Article
USB 2-layer PCB Routing Requirements for a USB Interface on a 2-Layer PCB In an earlier blog, I discussed some of the basic points in preparing routing rules for 2-layer PCBs to support routing and layout with digital signals. In particular, we looked at some of the basic stackup and routing rules needed to support a digital interface like I2C or SPI on a 2-layer PCB. When working with these interfaces, a few simple guidelines can help ensure signal integrity in your board and cut down on EMI. What about an impedance Read Article
