In The Mix: Tips For MIXED-SIGNAL DESIGN

摘要

In many cases, engineers have preconceived notions about mixed-signal designs and how analog and digital placement, partitioning and associated design should be performed. However, the truth of the matter is that every mixed-signal board design is different and demands interactive design negotiations between expert mixed-signal designers and the OEM customer. When laying out components for a mixed-signal PCB, certain considerations are critical to achieving optimum performance. Mixed-signal is particularly tricky to design since analog devices possess different characteristics compared to digital components: different power rating, current, voltage callouts and heat dissipation requirements, to name a few. Consequently, it is important for design engineers to recognize certain problematic areas and then implement them correctly in their mixed-signal designs.
