1.1.2. Connecting a Stratix V PCML Transmitter to Another Stratix V LVDS Receiver

The voltage levels are different for a pseudo current mode logic (PCML) transmitter and a low voltage differential signaling (LVDS) receiver.

However, since the LVDS receiver has a built-in common mode detector, you can directly connect the PCML transmitter output to the LVDS receiver input without using voltage divider circuits to match the voltage levels.
