Output Interfacing

The SCAN90CP02 outputs signals that are compliant to the LVDS standard. Their outputs can be DC-coupled to

most common differential receivers. Figure 12 illustrates typical DC-coupled interface to common differential

receivers and assumes that the receivers have high impedance inputs. While most differential receivers have a

common mode input range that can accommodate LVDS compliant signals, it is recommended to check

respective receiver's data sheet prior to implementing the suggested interface implementation.
