Hi Grant,
What was modified?
The doc is broken. I don’t see facsimile and I can’t download it.

Great! Looks good.

Hi Grant,
We are using 100uW drive capability crystal in our i.MX6 board. As per your power calculator excell, if we change the CL1 & CL2 capacitor value, we can achieve 200uW drive level with same 100uW crystal.
So will changing the CL1 & CL2 itself enough to achieve 200uW drive level in our board? or Do we need to change the crystal itself which supports 200uW drive level?

Per EB830: "A crystal is selected based on several parameters provided by the crystal supplier such that the crystal maximum drive level is not violated." So, a 100 uW crystal cannot be used above 100 uW because 100 uW is the maximum allowed dissipation. For example, this is similar to a 1/8 watt resistor -- this resistor shouldn't be used above the 1/8 watt maximum rating.
You must select capacitors to match your crystal's load capacitance on their data sheet while simultaneuously ensuring that the crystal's maximum power rating (uW) is not exceeded. The app note referenced in the bulletin shows how to calculate the load capactance; they refer to it as Ceq.
Hi,
Hi, are there any similar documents for the 32.768kHz Rtc crystal? In the datasheet i can only find the information that the ESR of the crystal must be <100kOhm but no spezifications how high the drive level is.

Within the doc EB830 is an attachment that I cannot seem to extract. IS this calculator available?
I can't use or download the attachment in the pdf file? What should I do to use it?
I have edited the post and added the embedded Excel document in zip file above.
