5.9 Timing Requirements (continued)

Maximum and minimum values are specified over the operating free-air temperature range and nominal supply voltages.

Typical values are specified at TA = 25°C, ADC sampling rate = 2.6 GSPS, 8x complex decimation single band, 50% clock

duty cycle, AVDD18 = 1.8 V, AVDD12, AVDDCLK, DVDD = 1.2 V and –1-dBFS differential input, unless otherwise noted
