3 / 20 page  REV. 0 –3– AD10226 Test Parameter Temp Level Min Typ Max Unit DYNAMIC PERFORMANCE Signal-to-Noise Ratio (SNR) 9 (Without Harmonics) fIN = 10.3 MHz 25 °CI 66.5 68.5 dBFS fIN = 49 MHz 25 °CV 67 dBFS fIN = 71 MHz 25 °CI 63 66 dBFS fIN = 121 MHz 25 °CV 64 dBFS fIN = 250 MHz 25 °CV 60 dBFS Signal-to-Noise Ratio (SINAD) 10 (With Harmonics) fIN = 10.3 MHz 25 °CI 65.5 68 dBFS fIN = 49 MHz 25 °CV 66.5 dBFS fIN = 71 MHz 25 °CI 62.5 65 dBFS fIN = 121 MHz 25 °CV 62.5 dBFS fIN = 250 MHz 25 °CV 59.5 dBFS Spurious-Free Dynamic Range 11 fIN = 10 MHz 25 °CI 76.5 82 dBFS fIN = 41 MHz 25 °CV 77 dBFS fIN = 71 MHz 25 °CI 66 72 dBFS fIN = 121 MHz 25 °CV 71 dBFS fIN = 250 MHz 25 °CV 70 dBFS Two-Tone Intermodulation Distortion 12 (IMD) fIN = 29.3 MHz; fIN = 30.3 MHz 25 °CV 78 dBc fIN = 150 MHz; fIN = 151 MHz 25 °CV 70 dBc Channel-to-Channel Isolation 13 fIN = 121 MHz Full IV 85 dB NOTES 1All ac specifications tested by driving ENCODE and ENCODE differentially, with the analog input applied to A INX1 and AINX2 tied to ground. 2SFDR enabled (SFDR = 1) for DNL and INL specifications. 3Gain error measured at 10.3 MHz. 4Input VSWR, see TPC 14. 5See Figure 1, Timing Diagram. 6t V and tPD are measured from the transition points of the ENCODE input to the 50%/50% levels of the digital outputs swing. The digital output load during test is not to exceed an ac load of 10 pF or a dc current of ±40 A. 7Supply voltages should remain stable within ±5% for normal operation. 8Power dissipation measures with encode at rated speed. 9Analog input signal power at –1 dBFS; signal-to-noise (SNR) is the ratio of signal level to total noise (first six harmonics removed). ENCODE = 125 MSPS, SFDR mode = 1. SNR is reported in dBFS, related back to converter full-scale. 10Analog input signal power at –1 dBFS; signal-to-noise and distortion (SINAD) is the ratio of signal level to total noise + harmonics. ENCODE = 125 MSPS. SINAD is reported in dBFS, related back to converter full-scale. 11Analog input signal equals –1 dBFS; SFDR is ratio of converter full-scale to worst spur. 12Both input tones at –7 dBFS; two-tone intermodulation distortion (IMD) rejection is the ratio of either tone to the worst third order intermod product. 13Channel-to-channel isolation tested with A channel/50 Ω terminated (A IN A2) grounded and a full-scale signal applied to B channel (A IN B2).
