5.10 Typical Characteristics (continued)

Typical values are at TA = 25°C, ADC sampling rate = 3 GSPS, DDC BYPASS mode (characterization mode only and not

supported operating mode to illustrate RAW ADC performance prior decimation), 50% clock duty cycle, AVDD18 = 1.8 V,

AVDD12, CLKVDD, DVDD = 1.2 V and –1-dBFS differential input, unless otherwise noted.
