AD9267 TYPICAL PERFORMANCE CHARACTERISTICS
All power supplies set to 1.8 V, 640 MHz sample rate, 0.5 V internal reference, PLL disabled, AIN = −2.0 dBFS, TA = 25°C, unless otherwise noted. The output spectrums shown in Figure 4 through Figure 9 were obtained after 16× decimation at the output of the AD9267 and are shown for a 10 MHz bandwidth.
