Hi Sir

May we must connect to EVM when we use TI Clock pro?

Because we have no EVM on hand.

may you pls help use TI Clock pro set CDCE949 Y2 output 66MHz，then output TXTfile to us for reference？

Hi Chen
You can use the Clockpro without connecting the EVM to generate your settings.
Let me know if you face any issue.
Best regards

Hi Chen
There is no need to pull down the VDDOUTs while sending I2C commands.
Your Clockpro config looks fine.
Are the other outputs switching?
