PLL outputs to drive 50 ohm loads

I need two outputs from a single PLL of CYCLONE-III 3C16. Both the outputs are single-ended. One of outputs is 100MHz and the other is 120MHz-200MHz which will be dynamically configured through NIOS-...

If you are driving a single load from each output consider using serial termination as it avoids the constant DC load of the parallel termination at the far side. In Cyclone III (and most other devices) series termination is easy.
