Hello.
I'm lost, I am about to design my first DDS circuit but...
The chip I will use have a max frequency for the clock of 180MHz,
I'm not sure I will use 180MHz but how do I get a clock with the right frequency?
I do understand that PLL's(Phase Locked Loop) have something to do with it but the more I read the less unclear it all becomes.
A simpe crystal oscillator will not do but I understand that a crystal will be the reference clock for the PLL or something.
Please can someone clarify, this regards to fixed frequency application ei a clock for a DDS chip.
Regards
