PRODUCTION DATA.
If the VDD_IN, VDD_PLL, VDD_LDO, VDD_DIG, and VDDO supplies are driven by the same 3.3-V supply rail that ramp in a monotonic manner from 0 V to 3.135 V, irrespective of the ramp time, then there is no requirement to add a capacitor on the PDN pin to externally delay the device power-up sequence. As shown in Figure 83, the PDN pin can be left floating, pulled up externally to VDD, or otherwise driven by a host controller for meeting the clock sequencing requirements in the system.
