AD9547 Reference input level

I need to use the AD9547 reference clock inputs in single ended mode. My reference input signal (that coming from user's) is a 50ohm AC coupled and can vary from -15 to +10dBm (50 ohm loaded).

How I can interface this signal to guarantee the AD9547 lock in entire level range? The expected solution is to use an amplifier and the a CMOS buffer, but what's the best solution to minimize the noise and jitter introduction due to signal conditioning?

Thanks.
