In cases where lowering the noise oor is paramount,
adding higher order lowpass or bandpass ltering can
signicantly increase signal-to-noise ratio. In Figure 13,
the LT6411 is shown driving an LTC2249 with a 2nd order
lowpass lter that has been carefully chosen to ensure
optimal intermodulation distortion. The response is
shown in Figure 14. The lter improves the SNR over the
unltered case by 6dB to 69.5dB. With the lter, the SNR
of the ADC and the LT6411 are comparable; better SNR
can be achieved by using either a higher resolution ADC
or additional ltering. Figure 15 shows the corresponding
SFDR of –75.5dBc with a 30MHz tone. Figure 16 shows
the 2-tone response of the LT6411 with 29.5MHz and
30.5MHz inputs. Note that 0dBFS corresponds to a 2VP-P
differential signal.
