it is my first time in use lock detect so i didn't now how to start.

how to define the lock detect?

I shouldn't worry about it, it's only AD2013 now, so there's plenty of time for someone else to deal with it later on.

In other words, WTF are you talking about!?

Post your links and references, don't expect us to google things for you, we might end up at the wrong place.

i didn't understand you.
in a C programing, i use a AD4350 for micrichip http://www.analog.com/static/importe...ts/ADF4350.pdf
and i dont know how to start.
i have afinished project.
in this project i nead to add the lock detect of this chip.
THANX.

Have you searched for a driver program from the manufacturer of the chip or board? Buyers are not expected to program their own driver.

That's not the only chip in your circuit surely.
Where is the micro-controller proper?

Anyway, did you read this

Now look at your schematic to find out where pin25 goes (from the ADF4350) to whatever micro-controller you're using.

When you know what pin on the micro-controller is used, you can write code to sample the pin value and determine if you have lock or not.
