Hi Martin, One question: Is your PLL unlock issue resolved now? How did you resolve it? I got the following information from Jim who helped you earlier to help you adjust the PHIA : "It’s probably not...

Hello Hooman, Regarding PLL lock I have mention it in my earlier post that when I first turn ON the LM98725 circuit and configure it the PLL remains unlock. It gives a random signal on output but when...
