AD9951 Clock Confusion

After looking through the datasheet for the AD9951 I am confused about the required voltage level on the clock pin when used single ended. The specification says that it should be 0 dBm but the input impedance of the clock pin is 1500 ohms. I always thought that dBm measurements should be made in a 50 ohm environment.


What voltage (in either Volts RMS or Volts Peak-to-Peak) should be seen at the AD9951 clock pin?
