Unless otherwise specified, the following specifications apply: AGND = DGND = DRGND = 0 V, VA = VD = 3.3 V, VDR = 1.8 V, Internal VREF = 1 V, fCLK = 155 MHz, VCM = VRM, CL = 5 pF/pin, Differential Analog Input, Single-Ended Clock Mode, Offset Binary Format. Typical values are for TA = 25°C. Timing measurements are taken at 50% of the signal amplitude. (1)(4)(5)(1)

(1) When the input voltage at any pin exceeds the power supplies (that is, VIN < AGND, or VIN > VA), the current at that pin should be limited to ±5 mA. The ±50-mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of ±5 mA to 10.
