Hi all,

 

I'd like to confirm the limitation of using i.MX6Q in 1.2GHz.

I have already read following thread but not enough for understand.

https://community.nxp.com/message/624063

 

In the note of Table 1 said

"If a 24 MHz input clock is used (required for USB), the maximum SoC speed is limited to 996 MHz.”.

 

On the other hand, In the note of Figure 1 said

"2. If a 24 MHz input clock is used (required for USB), the maximum SoC speed is limited to 792 MHz."

"3. If a 24 MHz input clock is used (required for USB), the maximum SoC speed is limited to 996 MHz.

I can't understand that I can use as a 1.2GHz when I input 24 MHz from external Crystal Oscillator.

 

Q1.

Can I use as a 1.2 GHz when I input 24 MHz from external Crystal Oscillator ?

 

Q2.

Can I use USB and 1.2GHz in the same time ?
