Input capacitance refers to the effective capacitance between one differential input pin and its complement.
3
Input resistance refers to the effective resistance between one differential input pin and its complement.
4
Standby power is measured with a dc input and the CLK± pin inactive (that is, set to AVDD or AGND).
