imx27 crystal specification

Hi,

I'm reviewing some piece of design around an IMX27, and I could not found the "Recommended External Crystal Specifications".

Does someone know where I could find this information?

as an example I found those kind of specification for IMX25 in this file : http://cache.freescale.com/files/dsp/doc/data_sheet/IMX25CEC.pdf?fr=gdc

but I could not find this information in IMX27 datasheets, maybe I missed a datasheet.

Thanks

Aurèle

26 MHz crystal requirements for IMX27 are te same as for i.MX25,

capacitance value for processor pin one can find in its ibis model.

Hi Traynard

i.MX27 documents have not such specs however one can use

i.MX25 specifications, they are valid for i.MX27 too.

I.MX processors share similar modules.

Best regards

Thanks for your helpful answer,

Concerning the high frequency quartz, as it is different on both products (24MHz for IMX25 and 26MHz for IMX27), the usage can't be the same. please tell me if i'm wrong.

is it possible to get the internal capacitance value for oscilators pin on IMX27?

thanks for your help
