Common use of Power Supply Noise Susceptibility Clause in Contracts

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 a 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.
