Power Supply Noise Susceptibility. A host system will supply stable power to the module and guarantee that noise & ripple on the power supply does not exceed that defined in Table 4-1. A possible example of a power supply filtering circuit that might be used on the host system is a PI C-L-C filter. A module will meet all electrical requirements and remain fully operational in the presence of noise on the 3.3V power supply which is less than that defined in the table 4-1. The component values of power supply noise filtering circuit, such as the capacitor and inductor, must be selected such that maximum Inrush and Turn-off current does not cause voltage transients which exceed the absolute maximum power supply voltage, all specified in Table 4-1.

Power Supply Noise Susceptibility. 39 A host system will supply stable power to the module and guarantee that noise & ripple on the power supply 40 does not exceed that defined in the table. A possible example of a power supply filtering circuit that might be 41 used on the host system is a PI (proportional integral) C-L-C filter. A module will meet all electrical 42 requirements and remain fully operational in the presence of noise on the 3.3V power supply which is less 43 than that defined in the table 4-1. The component values of power supply noise filtering circuit, such as the 1 capacitor and inductor, must be selected such that maximum Inrush and Turn-off current does not cause 2 voltage transients which exceed the absolute maximum power supply voltage, all specified in Table 4-1.
