VDD_ESAI_SPDIF i.MX 8X CPU VDD_ESAI_SPDIF_1P8_2P5_3P3 Input power
supply for ESAI0
and SPDIF0
interfaces.
VDD_SPI_SAI i.MX 8X CPU VDD_SPI_SAI_1P8_3P3 Input power
supply for SAI0,
SAI1, SPI0 and
SPI2 interfaces.
VDD_QSPI0B i.MX 8X CPU VDD_QSPI0B_1P8_3P3 Input power
supply for QSPI0B
interface.
VDD_CSI i.MX 8X CPU
n VDD_TMPR_CSI_1P8_3P3
n VDD_CSI_1P8_3P3
Input power
supply for CSI
interface.
USB_OTG1_VBUS i.MX 8X CPU USB_OTG1_VBUS Input power
supply for the
USB1 interface
VBUS.
Two additional power domains of the CPU are connected to the module LGA pads:
n VDD_PCIE_DIG
n NVCC_MIPI_CSI_DSI
These power domains are powered internally in the SOM and must not be connected to external
circuitry unless otherwise noted.
