Description
OTP 3.3V supply
1.2V core supply for WLAN
1.8V–3.3V supply for WLAN. Must be directly
connected to PMU_VDDIO and BT_VDDIO on the
PCB.
1.2V core supply for BT
1.8V–3.3V supply for PMU controls. Must be directly
connected to VDDIO and BT_VDDIO on the PCB.
1.8V–3.3V supply for SDIO pads and PCIe out-of-
band signals.
IO supply for RF switch control pads (3.3V).
1.2V supply from VOUT_CLDO (341, 352, 357).
1.2V supply from VOUT_CLDO (341, 352, 357).
Baseband PLL supply.
1.2V supply for PCIe PLL. (This pin should be left
unconnected (NC) for SDIO operation.)
1.2V supply for PCIE TX and RX. (This pin should be
left unconnected (NC) for SDIO operation.)
Supply the same voltage to this pin as that used for
the PCIE out-of-band signals (that is, PCIE_PME_L).
