OUTPUT INTERFACING
The DS90LV004 outputs signals that are compliant to the LVDS standard. Their outputs can be DC-coupled to
most common differential receivers. Figure 6 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.
