Hi all

 

Let me confirm about the 24MHz Crystal Oscillator requirement for i.MX7.

I try to find some requirement in datasheet and reference manual but I can't.

On the other hand, some recommendations for other i.MX series are available in community etc,.

 

 

What data we need is "center frequency" , "Tolerance", "CL", "ESR" and "Max drive level".

 

Could you answer me whether those recommendation ca apply for i.MX7 or not ?

Please check following question.

 

1. For center frequency,

I found a following description in Section 4.8 XTAL Electrical Specifications of IMX53CEC

 

Can it apply for i.MX7 ?

 

2.For Tolerance

I found a folllowing description in section 2.5. Oscillator tolerance of http://www.nxp.com/assets/documents/data/en/user-guides/IMX7DSHDG.pdf.

 

which tolerance value is your recommendation if user don't use above three interface ?

 

3. For CL & ESR:

I found following thread.

https://community.nxp.com/message/337037

 

Can it apply for i.MX7 ?

 

4. For Max drive level

I found following description in table 1 of http://cache.nxp.com/assets/documents/data/en/engineering-bulletins/EB830.pdf?

 

Can it apply for i.MX7 ?
