Does anyone have mathcad code to design 4th-order or 5th-order charge pump PLL.

thanks a lot for your help.
 

Yes, I checked the website, but most of them are for 3rd-order PLL.
 

Go to National Semiconductor and download Dean Banerjee's PLL app note/book. Detail's on how to calculate 4th and 5th order PLL's. It's not in Mathcad, but it won't take you more than 1 afternoon to type it all in. (Assuming Mathcad doesn't crash ! )
