OUTPUT INTERFACING
The DS10CP154A 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 accomodate LVDS compliant signals, it is recommended to
check respective receiver's data sheet prior to implementing the suggested interface implementation.
