Dual, 96Msps, 14-Bit, IF/Baseband ADC
ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3.3V, OVDD = 2.0V, GND = 0, REFIN = REFOUT (internal reference), CL ≈ 10pF at digital outputs, VIN = -1dBFS (differential),
DIFFCLK/SECLK = OVDD, PD = GND, SHREF = GND, DIV2 = GND, DIV4 = GND, G/T = GND, fCLK = 96MHz (50% duty cycle), TA =
-40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: Specifications ≥ +25°C guaranteed by production test, < +25°C guaranteed by design and characterization.
Note 2: During power-down, D0A–D13A, D0B–D13B, DORA, DORB, and DAV are high impedance.
Note 3: Data outputs settle to VIH or VIL.
Note 4: Guaranteed by design and characterization.
