Typical Characteristics (continued)

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 ADC sampling rate = 2.6 GHz, 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)

fIN = 1.85 GHz, AOUT = –2 dBFS, AVDD19 = 1.8 V,

ADC sampling rate = 2.5 GHz

Figure 33. HD2 Histogram at AVDD19 = 1.8 V

fIN = 1.85 GHz, AOUT = –2 dBFS, AVDD19 = 1.9 V,

ADC sampling rate = 2.5 GHz

Figure 34. HD2 Histogram at AVDD19 = 1.9 V

fIN = 1.85 GHz, AOUT = –2 dBFS, AVDD19 = 2.0 V,

ADC sampling rate = 2.5 GHz
