Dear All,
In i.MX6 Solo.
My customer uses a 24MHz external oscillator, and inputs and has the signal to XTALI.
And they will connect an oscillator output to a XTALI input pin.
In this case, can NVCC_PLL_OUT be used as a power supply for an oscillator?
Current needed for the oscillator is about 2.5mA~4.5mA.
Or should a power supply be prepared independently?
Best Regards,
George

Hi George
I am afraid such schematic is not available.
Probably one can use NVCC_PLL_OUT as reference
voltage using external analog comparator.

Hi George
not, it can not be used.
From Table 2-6. Power and decouple recommendations p.20
IMX6DQ6SDLHDG, Hardware Development Guide
"These LDOs should only be used to power the loads as
described in the reference manual or data sheet. Do not
connect any loads to these LDO outputs:"

Dear chip,
OK.
Please let me know the recommendation schematics in the case of using an external oscillator.
