Si570 LVDS Output Impedance

Alfredo Mendiola Loyola


If I connect a Center Tap of an 1:4 Transformer (Secondary) to the LVDS outputs I will get a 50 Ohm output impedance on the Primary?


I understand that the output impedance of each output of the si570 is 100 Ohm (LVDS), When I connect each output of the si570 to the transformer Secondary I will get 200 ohm and 50 ohm on the Primary (200 4 = 50 ohm).

Do I have to connect the center tap of the secondary to ground?
