Output Interfacing
The DS25BR440 outputs signals compliant to the LVDS standard. Its outputs can be DC-coupled to most
common differential receivers. The following figure 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 the
respective receiver's data sheet prior to implementing the suggested interface implementation.
