clock generator and synthesizer

Hi Lord

Thank you for the answer. I am given a project to simulate a clock generator. But my lecturer mentioned to me I must use a clock generator instead of a clock synthesizer. I do not know what does it mean. I am hoping I can get more advice from this group before I ask my lecturer for more details. Can you give me some important point that I can ask my lecturer in order to know more of what a clock generator is different from clock synthesizer to avoid getting the wrong circuit?

PLL based clock generator has a phase detector, Low pass filter, cmos charge pump and a buffer? Does it come with a frequency divider? How about PLL based clock synthesizer?

Kindly enlighthen Thank you so much

It seems to me that a synthesizer is producing its output from a higher or lower frequency source. A clock generator may simply be a buffered oscillator output. This kind of hair splitting seems rather unimportant, why do you ask?

The way you're _supposed_ to do it is to ask the lecturer for the details if they're not clear to you. His job is to make you understand, and if he can't, or won't, answer your questions, then he is simply not doing his job. If you don't bother to ask, then you're not doing your job as a student.

Nobody here can have any better idea of what your lecturer wants than he does, so we'd be making stuff up.

Go ask the teacher.

Good Luck! Rich

Thank you Rich! :)

Well said I look forard to get the exact goal so I can work on it and come back here for discussions Cheers

Doing just that might be the most valuable part of your education - that is, learning to pump for details until you get a crystal-clear understanding of the task at hand. Well, at least a clear description. :-)

Good Luck! Rich
