Mixed Signal Design Considerations
Designs with analog, digital and RF features challenge the PCB designer to reduce noise, improve EMI performance and lower distortion.
The layout of an efficient mixed-signal design can be both time consuming and challenging. However, diligently working on this type of layout can result in a system with less crosstalk, more noise immunity and better EMI performance. The PCB industry continues gearing toward higher speeds, miniaturized components and denser circuits, and consequently, the coexistence of digital and analog technologies in close proximity has become unavoidable. Add to this an element of RF circuitry, and the designer’s job has just become a bit more difficult.
