swing of the signal applied to the active input must exceed the specified minimum Differential Input Voltage Swing (VID
min) and the unused input must be ac coupled to ground. When driving differentially, the difference between the positive
and negative input signals must exceed VID min. (Each individual input signal needs to swing only half of this range.) In
either case, the voltage applied to any individual pin (DIN+, DIN–, REFCLK+, or REFCLK–) must not exceed the
specified maximum Input Voltage Range (VIS max).
