Analog Front-End
ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3V, OVDD = 1.8V, internal reference (1.024V), CL ≈ 10pF on all digital outputs, fCLK = 11MHz (50% duty cycle), Rx ADC input
amplitude = -0.5dBFS, Tx DAC output amplitude = 0dBFS, differential Rx ADC input, differential Tx DAC output, CREFP = CREFN =
CCOM = 0.33µF, unless otherwise noted. CL < 5pF on all aux-DAC outputs. Typical values are at TA = +25°C.) (Note 1)
