65Msps, 12-Bit, IF Sampling ADC
Typical Operating Characteristics (continued)
(VDD = 3.3V, OVDD = 2.0V, GND = 0, REFIN = REFOUT (internal reference), CREFOUT = 0.1µF, CL ≈ 8pF at digital outputs, differential
input at -0.2dBFS, CLKTYP = high, PD = low, G/T = low, fCLK = 65.005678MHz (50% duty cycle), CREFP = CREFN = 0.1µF in parallel
with 10µF to GND, 10µF between REFP and REFN, CCOM = 0.1µF in parallel with 2.2µF to GND, TA = +25°C, unless otherwise noted.)
