1 Measured using a 10 MHz, 0 dBFS sine wave, and 100 Ω termination on each LVDS output pair.
2 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 using a dc input and the CLK pins inactive (set to AVDD or AGND).
