Hello! Yes, I am a neophyte. ![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I am contemplating a PLL that would need to multiply the frequency of a low Hz pulse by 200. Is this possible/practical, or do I need multiple PLL stages.
Or are there better ways to proceed?
Also, how does one know if a part is obsolete? I saw on one forum (this one?) a guy mentioning an old EPROM he was going to use. People laughed at him (nicely) about raiding the Smithsonian for parts.
But how does a beginner know if a component is out of date?
