6.13 Typical Characteristics

Unless otherwise noted, these specifications apply for VA3.0 = 3.0 V; VA1.8 = 1.8 V; VA1.2 = 1.2 V; FCLKIN = FS = 250 MSPS;

240-MHz input frequency; –3-dBFS input power. External termination at ADC input is 66

Ω differential. CLKIN± input is a 2

Vp-p differential sinusoid. Typical values are at TA = 25°C.
