... Power supply bypassing is required at the input and output supply pins (see Figure 28). The power supply section of the ADM3053 uses a 180 MHz oscillator frequency to pass power efficiently through its chip-scale transformers. In addition, the normal operation of the data section of the iCoupler introduces switching transients on the power supply pins ...
