Output Interfacing

The DS25CP152Q outputs signals that are 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.
