Thevenin Equivalent Termination
Design PCB traces for 50 ohm characteristic impedance
To use multiple supply voltages requires level translation. Direct circuit connection is not valid.
Mixed supply voltages are allowed. No translation is necessary. (ECL is returned to the most positive
supply and this is common to all circuits)
Mixed supply voltages are allowed. LVDS signal levels are power supply independent.
3.3 V LVDS oscillators properly interface 2.5 V Logic Arrays for example.
