Out of the four Power supply rails mentioned above, the 1.0 V and the 1.8 V supplies are sensitive to the supply ripple and noise because these supplies feed the critical blocks in the device like PLL, baseband ADC, synthesizer, and so forth. For more details on the power supply rail and the logic that it feeds in the device, see the device-specific data sheet. Table 2-1 and Table 2-2 provide the ripple and noise spec for 1.0 V
