Hello,

I am currently evaluating the CY2941x/CY2942 for a serdes application and I would need the documentation on how to program it without using the Clock Wizard.

For this application, it is not feasible to use the one-time programming but we need to able to program the chip in mission mode using I2C from a microcontroller.


I have gone through all the documents that I could find on this topic but important pieces are missing. The closest thing I found was the application note "AN210253_CY294xx_High_Performance_Clock_Getting_Started_and_Best_Design_Practices-ApplicationNotes-v03_00-EN.pdf" but it only explains how to do small frequency changes (+/- 500 ppm) and not how to do the "large change" frequency programming.


Where can I find the complete documentation on how to program the large change?

Many thanks in advance,
Best regards

Hi @celmen_cisco ,

The programming specifications are confidential and cannot be shared on the public forum. If you require the documentation you will need to have a NDA with the company. 

Thanks,

Pradipta.
