Hi, communty,

 

I have a question about i.MX6DQ external crystals.

Do you know how long times is needed to stabilize the oscillation of external crystals (32.768kHz & 24MHz) from the timing VDD_SNVS_IN is supplied?

 

Actually, a customer will add delay to POR_B and release POR_B after external crystals oscillation is stable, because reraly i.MX6 cannot boot if POR_B is released before external crystal oscillation.

To understand how much delay should they add, the data is needed.
