21 / 33 page ![]() Data Sheet AD9082 Rev. A | Page 21 of 33 TYPICAL PERFORMANCE CHARACTERISTICS DAC TA = 25°C using the AD9082-FMCA-EBZ, data curves represent average performance of all DAC outputs with harmonics (or alias harmonics) and spurs falling in the first DAC Nyquist zone (<fDAC/2), IOUTFS = 26 mA, PLL clock multiplier enabled, and ADC powered down, unless otherwise noted. See the UG-1578 user guide for additional information on the JESDB or JESDC mode configurations. –50 –100 –95 –85 –75 –65 –55 –90 –80 –70 –60 0 3000 2500 2000 1500 1000 500 fOUT (MHz) 0dBFS –7dBFS –12dBFS –17dBFS Figure 6.
