Hi

I connected 3.3V to the NVCC_PLL pin.
Will i.MX6ULL work?
Could you tell me the meaning of NVCC?

best regard.

Hello,

   i.MX 6ULL NVCC_PLL  is internal LDO output of 1.1 V - only capacitors (1×0.22uF+1×10uF)
should be connected with it. External voltage of 3.3V to the NVCC_PLL pin - definitely  is not
acceptable.

Regards,
Yuri.

Hi

What if I don't connect a capacitor?

Will it happen that it does not oscillate without a capacitor?

LDO outputs require some capacitors to get stable voltage.

Hi

Thank you for your reply.
Does the installed capacitor act as a bypass capacitor?
