Figures 35–38 combine the dual-tone SFDR as well as single
tone SFDR and SNR performance at IF frequencies of 45 MHz,
70 MHz, 85 MHz and 135 MHz. Note, the SFDR vs. ampli-
tude data is referenced to dBFS while the single tone SNR data

tial mode (via transformer) with a 1 V span. The analog sup-
ply (AVDD) and the digital supply (DRVDD) were set to +5 V
and 3.3 V, respectively.
