*Note: The CLKIN 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 (V_ID
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 V_ID min. (Each individual input signal needs to swing only half of this
range.) In either case, the voltage applied to any individual pin (CLKIN+, CLKIN–, REFCLK+, or REFCLK–) must not
exceed the specified maximum Input Voltage Range (V_IS max).
