4 / 20 page  AD10678 Rev. C | Page 4 of 20 AC SPECIFICATIONS AVCC = 5 V, EVCC = 3.3 V, VDD = 3.3 V, TA = 25°C, differential encode = 80 MSPS, CLOAD ≤ 10 pF, unless otherwise noted. Table 3. Parameter Test Level Min Typ Max Unit SNR1 Analog Input 2.5 MHz I 77.5 80.5 dBFS @ −6 dBFS 10 MHz I 77.5 80.5 dBFS 30 MHz I 77 80.2 dBFS 70 MHz I 76 78 dBFS SINAD2 Analog Input 2.5 MHz I 77.2 80.3 dBFS @ −6 dBFS 10 MHz I 77.2 80.3 dBFS 30 MHz I 76.6 79.7 dBFS 70 MHz I 74.7 77.4 dBFS SFDR3 Analog Input 2.5 MHz I 88 97.2 dBFS @ −6 dBFS 10 MHz I 88 97.2 dBFS 30 MHz I 84 94.2 dBFS 70 MHz I 81 91.7 dBFS TWO-TONE4 Analog Input @ −7 dBFS IMD f1 = 10 MHz, f2 = 12 MHz V 96 dBFS f1 = 70 MHz, f2 = 72 MHz V 84 dBFS 1 Analog input signal power at −6 dBFS; signal-to-noise (SNR) is the ratio of signal level to total noise (first five harmonics removed). Encode = 80 MSPS. SNR is reported in dBFS, related back to converter full scale. 2 Analog input signal power at −6 dBFS; signal-to-noise and distortion (SINAD) is the ratio of signal level to total noise + harmonics. Encode = 80 MSPS. SINAD is reported in dBFS, related back to converter full scale. 3 Analog input signal equals −6 dBFS; SFDR is the ratio of the converter full scale to the worst spur. 4 Both input tones at −7 dBFS; two-tone intermodulation distortion (IMD) rejection is the ratio of either tone to the worst third-order intermodulation product. |
