6.9 Digital Requirements

typical values are specified at an ambient temperature of 25°C; minimum and maximum values are specified over an ambient

temperature range of –40°C to +85°C; and chip sampling rate = 2949.12 MSPS, DDC bypassed performance, 50% clock duty

cycle, AVDD19 = 1.9 V, AVDD = 1.15 V, DVDD = 1.15 V, –2-dBFS differential input, and 0-dB digital gain (unless otherwise

noted)
