If there is no constrain, you could multiple the Clock with 2*pi*f, where f is your frequency and then feed it to an "Interpreted MATLAB Fcn" block where you specify it as "sin" or "sin(u)". You could implement "f" as a constant, or a parameter or an Inport.

but i need to take the frequence as an random variable between 50 and 250 Hz ??

then multiply the Clock with 2*pi and the Random Number block.
