I am busy with synchronize all my ADCs on data acquisiton systems. My ADCs need to clock signals for their duty. So in my opinion for synchronization, if i send to all my ADCs clock signal which is driven by 1 a GPS with accurate 1PPS output, it can be be synchronous with each other. So i am looking for a knowledge or a component which do that timing job. My ADCs need to 24.576 mHz Clocking signal with accurate GPS PPS signal. How can i do that? Do you have a solution or any idea for that?
Thank you for all your reply. But i want to give you a detailed explanation below;
I have two data acquisiton device which includes ADCs on their own (MAX11040K maxim integrated). And each system has 4 ADCs. There is no connection between those systems (no cable, no wireless connection). They are totally seperate from each other. I want to put one of those systems on somewhere in England, and i start to system for data acquisition. And i want to put other one on somewhere in Germany. And i start to system for data acquisiton too.
Now i want to watch these raw data ( which comes from ADCs) on systems by an software in USA. I want to see raw data on both of these devices at the same time. So i need to know "time knowledge" with raw data. I can do that by putting a GPS Receiver Module on each systems. GPS gives me a Peak Per Second signal which is valid all over the world. Beause it has Real Time Clock signal. All GPS Receiver Modules in the world produce PPS signal at the same time. I want to use that signal for sychronization. I need to trigger a circuit with that PPS signal only at start. By this way, Triggered circuit can produce a 24.576 mHz signal for my ADCs clock signal. So all systems work synchroniza to each other. This is a theory what i want to do.
Sychronization can be done with two way;
The first one;
I put a crystal for every ADCs on two device, and if i push the start buttons of seperated systems at the same time, systems will work sychronizally with each other. And i can watch raw data on USA by a software. But this never can happen because of systems located different countries.
The second way which i need to help for this;
The ADCs, which is in DAQ system, need 24.576 mHz clock signal. if I design a circuit which is triggered by GPS PPS signal, the circuit can produce a 24.576 mHz clock signal for my ADCs. The ADCs works without a crystal. This circuit which i planned provide them for synchronized clock signal. After that i can watch systems on USA.
Now the circuit which i need to has one input (PPS signal) and one output which is accurate GPS PPS signal.
Finally, how can i create this circuit?
