Typical Operating Characteristics

(AVDD = 3.3V, DVDD = 1.8V, INP and INN driven differentially, internal reference, CLKP and CLKN driven differentially, CL = 5pF at

digital outputs, fCLK = 80MHz, TA = +25°C. Unless otherwise noted, all AC data based on 32k-point FFT records and under coherent

sampling conditions.)
