Note 1: All voltages are referenced to ground. Currents entering the IC are specified positive and currents exiting the IC are negative.
Note 2: Supply current measured with C_L = 15pF, V_CC = 3.6V, T_A = 25°C, f_OUT = 66.6MHz, no dither.
Note 3: No dither.
Note 4: Guaranteed by design.
Note 5: For aging characteristics, contact factory.
(T_A = +25°C, V_CC = 3.3V, unless otherwise noted.)
