OUTPUT INTERFACING
The DS25BR120 outputs signals compliant to the LVDS standard. It 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 datasheet prior to implementing the suggested interface implementation.
