Output Interfacing
The DS25BR440 outputs signals compliant to the LVDS stan-
dard. Its outputs can be DC-coupled to most common differ-
ential 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 rec-
ommended to check respective receiver's data sheet prior to
implementing the suggested interface implementation.
