Delay Tuning for High Speed Signals: What You Need to Know Delay Tuning for High Speed Signals: What You Need to Know Length matched lines in a PCB Take a look at two signal readouts on an oscilloscope, and you can see how length/timing mismatches between signal traces can improperly trigger downstream gates. The situation becomes worse when we look at the travel time for a master clock signal and the roundtrip time for sent/received data in different computer interfaces. SDRAM has solved this nicely by placing a clock in the slave device and sending a clock Read Article
Why Impedance Matching is Important in Transmission Lines Why Impedance Matching is Important in Transmission Lines Do you know the transmission line critical length for these traces? Whether you are working with digital or analog signals, you’ll most likely need to match impedances between a source, transmission line, and load. The reason impedance matching is important in transmission lines is to ensure that a 5 V signal sent down the line is seen as a 5 V signal at the receiver. If you understand why transmission line matching is important, you can start to Read Article
Radiated EMI Sources in High Speed/High Frequency PCBs Radiated EMI Sources in High Speed/High Frequency PCBs The image above shows a snapshot of results from an EMC test under CISPR requirements (U.S. uses FCC certification requirements). This product is right at the edge of Class B limits on radiated emissions. We can see a very complicated resonance spectrum in this plot with a large number of sharp peaks superimposed on wide peaks at lower level. What causes all of this radiated noise? There a number of sources that can cause this type of emission Read Article

How Absorbing Conformal Coatings Affect Your PDN and Radiated EMI How Absorbing Conformal Coatings Affect Your PDN and Radiated EMI Signal integrity analysis and measurements go hand-in-hand I remember the first time I— back in my days of working with sensors—pumped nitrogen dioxide into a humid environmental chamber while evaluating a DUT. Over time, the surface of my copper leads slowly corroded as they sat unprotected in such a noxious environment. As my electronics experiment was living a double life as a chemistry experiment, I questioned whether to use a conformal Read Article
Power Integrity Measurements for Your Prototype Board Power Integrity Measurements for Your Prototype Board We often write about signal integrity and power integrity around here, but there is one area where we sometimes fall short: test and measurement. Both aspects of building a new device are critical for ensuring your board will work as intended and meets stringent performance requirements. With advanced systems, the level of testing and measurements required to qualify a prototype for full-scale production spans far beyond using a multimeter. Power Read Article
