Detail of AN-661 (Connecting Altera PLL and PLL Reconfig IP Core)

For BW settings, you can select the BW = low/medium/high within the calculator and the suitable hex value will be provided in the calculator. You will need to reconfigure the PLL based on the new hex value to achieve the specified BW.

Hi JwChin

Thank you for your reply.

I tried to use this excel file to calculate PLL parameters.

I want to set different value between Low Count and High Count on M counter.

However, I could not set it on this excel even if "Odd Division" is yes.

How do I calculate PLL parameter with my required ?

Thanks a lot,

Best regards,

Hmmm.....I am able to set it from the drop down list.

What value do you want to set for M counter high/low?

What error message are you seeing?

Can you send me your excel file?

> What value do you want to set for M counter high/low?

I'd like to set for M counter high as 5 and low as 4.

> What error message are you seeing?

I didn't see any error message.

I could not only select different counter div. between high and low.

I downloaded excel file from this URL.

Hi watari,

Im sorry the delayed response. I downloaded the excel from the same link as well.

I am able to set it as screenshot.

I am not sure if this is an Excel issue on your PC. Would you be able to try on a different PC?
