plane. Differential traces are routed together with a minimal gap between them so that noise events affect
them equally and are rejected as common mode noise.
Analog signal connections into the CS3301A/02A amplifiers are 2-wire IN+ and IN- differential pairs, and
are routed as such. Analog signal connections out of the CS3301A/02A amplifiers and into the CS5372
modulators are 4-wire INR+, INF+, INF-, INR- quad groups, and are routed with INF+ and INF- as a tra-
ditional differential pair and INR+ and INR- as guard traces outside the respective INF+ and INF- traces.
