E | Page 7 of 45 AD9250-170 AD9250-250 Parameter1 Temperature Min Typ Max Min Typ Max Unit TWO-TONE SFDR fIN = 184.12 MHz (−7 dBFS), 187.12 MHz (−7 dBFS) 25°C 87 84 dBc CROSSTALK2 Full 95 95 dB FULL POWER BANDWIDTH3 25°C 1000 1000 MHz 1 See the AN-835 Application Note, Understanding High Speed ADC Testing and Evaluation for a complete set of definitions. 2 Crosstalk is measured at 100 MHz with −1.0 dBFS on one channel and no input on the alternate channel. 3 Full power bandwidth is the bandwidth of operation determined by where the spectral power of the fundamental frequency is reduced by 3 dB. DIGITAL SPECIFICATIONS AVDD = 1.8 V, DRVDD = 1.8 V, DVDD = 1.8 V, maximum sample rate for speed grade, VIN = −1.0 dBFS differential input, 1.75 V p-p full-scale input range, DCS enabled, link parameters used were M = 2 and L = 2, unless otherwise noted.
