Table 4-2 shows the measured SNR performance of the ADC12DJ3200-SP at various frequencies for –1-dBFS differential inputs and dual channel mode (JMODE3). The comparison between the measured SNR with the ADC12DJ3200EVMCVAL onboard clocks and with TIDA-010191 clocks shows almost similar performance. Figure 4-9 through Figure 4-11 show the spectral results at a 3200-MHz sampling frequency in single-channel mode.
