TYPICAL CHARACTERISTICS
At +25°C, AVDD = 1.8 V, AVDD_3V = 3.3 V, DRVDD = 1.8 V, IOVDD = 1.8 V, f_S = 153.6 MSPS, sine-wave input clock,
1.5-V_PP differential clock amplitude, 50% clock duty cycle, –1-dBFS differential analog input, 16-mA CML current, and 32k-
point FFT, unless otherwise noted. Note that after reset, the device is in 0-dB gain mode.
