Hi expert,

Our design don't have MIPI/RGMII/SD2/SATA/LVDS/HDMI/PCIE device。

First question：We want to delete the power supply of some pins.

Can we delete this power supply? if not , can we delete this capacitors？

1.NVCC_MIPI

2.NVCC_RGMII

3.NVCC_SD2

4.SATA_VP , SATA_VPH

5.NVCC_LVDS2P5

6.PCIe_VP AND PCIe_VPTX ,PCIe_VPH

7.HDMI_VP AND HDMI_VPH

Second question ：Can we delete this precision resistances?

1.PCIe_VPREXT

2.HDMI_REF

3.CSI_REXT/DSI_REXT

Thanks,

BR，

Alyssa

Hi Alyssa

all power supplies should be provided to processor

(even some modules are not used), exceptions are given

in sect.2.8 Unused analog interfaces

i.MX6 System Development User’s Guide (rev.1, 6/2013)

Best regards
