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.
2.5.3 Bypass Capacitors
Each device power supply pin includes 0.1 µF bypass capacitors placed as close as possible to the pin
on the back side of the PCB. Each power supply net includes at least 100 µF bulk capacitance as a charge
well for transient current loads.
