and 1:4 Demultiplexed LVDS Outputs
Typical Operating Characteristics (continued)
(V_CCA = V_CCI = V_CCD = 5V, V_CCO = 3.3V, V_EE = -5V, GNDA = GNDI = GNDD = GNDO = GNDR = 0V, f_CLK = 2.21184Gsps, analog
input amplitude at -1dBFS differential, clock input amplitude 10dBm differential, digital output pins differential R_L = 100Ω. Typical
values are at T_J = +105°C, unless otherwise noted.)
