Differential Pair Routing for SI and EMI Control

Differential pairs have been used in PC boards for years to carry high-speed serial and high-speed parallel data, in a variety of bus formats. Many board designers and engineers believe the rules... [more]

Designing the Signal Return Path

When designing a PCB, the signal routing and its return are critical to the circuit working properly. Great care is usually given to routing the signals, but often the return portion is the last... [more]

IoT PC Board Design and Layout

Circuit boards for the IoT world (Internet of Things) are often driven by the need for low power dissipation, low cost (which drives very low layer count), moderate to high-density and mixed-signal... [more]

Routing Digital Boards to Avoid Problems

There are many ways to route a PCB, some much more effective for signals than others. The first design rule is that the board must work properly, so it is important to have a plan that addresses... [more]
