Spotting DDR4 Impedance Violations in High Speed PCB Design
High speed interfaces can be difficult to layout and route without the right set of design and analysis tools. Protocols like Ethernet, USB, DDR, MIPI, and others require precise single-ended and differential impedance control in your PCB layout. This, in turn, requires designing a stackup for controlled impedance routing with defined trace geometry and return path. It’s no wonder some designers have a hard time getting started with high speed...
