CDB5378

DS639DB3

Analog signal connections into the CS3301/02 amplifiers are 2-wire IN+ and IN- differential pairs, and are

routed as such. Analog signal connections out of the CS3301/02 amplifiers and into the CS5373A mod-

ulator is a 4-wire INR+, INF+, INF-, INR- quad group, and is routed with INF+ and INF- as a traditional

differential pair and INR+ and INR- as guard traces outside the respective INF+ and INF- traces.

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.
