about the input clk of AD9748

Hi, I have looked up the datasheet of AD9748, and I find the 'differential voltge ' character of Input Clk. The  'differential voltge ' character in the datasheet is 500mv minmum and 1.5V in typical. I need to find a  LVDS Clock distributor to offer the clk to AD9748. However, I find the character 'output differential voltage' of LVDS  CLK OUTPUT in the datasheet of most of the distributors in your company is 454mV maximum.

Can you tell me whether the 'differential voltge ' character  is the same as the  'output differential voltage' ? And are they meanings same as the swing of differential ?

Can you suggest a   LVDS Clock distributor  to AD9748?
