Other Parts Discussed in Thread: ADS1274

I have a question, what is the maximum external AHCLK that mcasp can handle? I have searched through TRM to find it but found nothing

Can the development team help me answer this? Thank you.

Hello ,

Thank you for the query.

Can you please tell which operating performance points (OPP) mode is used?

Also, kindly help me to understand the use-case

Regards

Hi Rajashri, thanks for the response. I use OPP100. I've found the answer in the SPRS717J docs. The maximum clock for AHCLK is 50Mhz. I am using MCASP to communicate with ADS1274.

Hello Bayu Eko,

The value of 50MHz for AHCLK in OPP100 seems to be correct.

Thanks for the update.
