*Note: The DIN and REFCLK inputs may be driven differentially or single-endedly. When driving single-endedly, the voltage 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).
